Conference Close Message from IEC2M Organizing Team
Warmest congratulations on the success of the 1st International Electronic Conference on Metallurgy and Metals (IEC2M). Many thanks for your participation.
All participants of IEC2M are welcome to submit the extended work to the Metals Special Issue "Selected Papers from the 1st International Electronic Conference on Metallurgy and Metals (IEC2M 2021)".
The winners of IEC2M Best Paper Award and Best Poster Award will be announce on 20th March 2021.
Welcome from the Chair
It is my pleasure to invite you to join the 1st International Electronic Conference on Metallurgy and Metals (IEC2M) that will be hosted online at https:sciforum.netconferenceIEC2M
Metallurgy and Metals play a crucial role in current technology and have critical importance in addressing major societal challenges. Among them, process metallurgy (i.e., extracting metals from their ores to make refined alloys), physical metallurgy (i.e., shaping, alloying, heat treatment, joining, corrosion protection, and testing of metals), and critical metals recovery from secondary waste streams are of outstanding importance. IEC2M will present the state-of-the-art of Metallurgy and Metals related to these issues.
IEC2M 2021 will promote and advance the exciting and rapidly changing field of Metallurgy and Metals. Topics of interest include, but are not limited to the following:
2. Powder Metallurgy
3. Corrosion and Protection
4. Biobased and Biodegradable Metals
5. Metal Forming
6. Additive Manufacturing
7. Metal Failure
8. Metal Recycling
IEC2M 2021 will enable you to share and discuss your most recent research findings with the worldwide vibrant community of scientists and engineers in the field.
IEC2M 2021 will make your presentation accessible to hundreds of researchers worldwide, with the active engagement of the audience in question and answer sessions and discussion groups that will take place online.
Submitted abstracts will be reviewed by the conference committee. The authors of accepted contributions will be invited to produce an extended abstract for the conference proceedings along with a slide presentation of their work. Following the conference, outstanding contributions will be invited to be submitted for publication in Metals.
IEC2M 2021 is a new and exciting experience for me that I believe this event will contribute to the dissemination of knowledge despite the situation regarding Covid-19. IEC2M 2021 will contribute to the dissemination of research in an online environment that will maintain the same standards and structure of traditional conferences but will be more inclusive by eliminating the cost and time barriers that prevent participation in physical events.
I hope you will join us and present your work at IEC2M 2021, and be part of this exciting online experience.

Leaching kinetics of tellurium, selenium and silver from copper anode slime by sulfuric acid leaching in the presence of manganese(IV) oxide and graphite

Submitted: 07 Jan 2021
Abstract: Show Abstract
|, , , ,||N/A||
Leaching of constituent metals from copper anode slime/CAS (22.23% Se, 1.53% Te, 9.66% Ag) by sulfuric acid in the presence of manganese(IV) oxide (MnO2) and graphite has been investigated at a range conditions by varying stirring speed (200–600 rpm), H2SO4 concentration (0.5–3.0 M), MnO2/CAS and graphite/CAS mass ratio (0–1/1) and temperature (25–90 °C). The metal leaching was facilitated by the galvanic interaction with MnO2, while graphite play role as a catalyst. Under the most suitable conditions (500 rpm, 2.0 M H2SO4, 0.8/0.8/1 MnO2/graphite/CAS mass ratio and 90 °C temperature), the extent of leaching of Se, Te and Ag from the CAS, together with Mn from MnO2 after 6 h was 90.8%, 81.9%, 80.7% and 84.1%, respectively, as compared to 76.8% Te, 69.4% Se, 67.2% Ag and 55.9% Mn after leaching of CAS with MnO2 without graphite under the similar conditions, and against still lower leaching in the absence of MnO2 (32.6% Te and negligible Se and Ag). The leaching results (CAS+MnO2+graphite) of tellurium and silver at temperature 25–50 °C well fitted to the mixed and surface chemical reaction models, respectively, and changed to follow the diffusion and mixed control models in the temperature range 60–90 °C with the respective apparent activation energies of 17.8 and 12.2 kJ/mol. That of selenium was controlled by the surface chemical reaction with the estimated activation energy of 27.6 kJ/mol in the temperature range 25–90 °C. And manganese leaching followed the mixed-control model (activation energy of 56.7 kJ/mol) at the all tested temperature.

Two main problems faced by the increasingly technological society are the huge amount of waste that humans generate and the scarcity or criticality of many of the materials used. In this sense, one of the EU's priorities is to promote the transition to a circular economy, where the materials and products manufactured with them are kept in the life cycle as long as possible. Among the strategic materials, Niobium, Tantalum and Rare Earth Elements (REE) are included in the 2020 year list of the 30 critical raw materials of European Union due to their importance for high-tech products and emerging innovations and the risk in the security of supply and economic importance.
In this work, the oxides of two of these strategic materials, Niobium and Tantalum, are recovered from the tailings of the Penouta Sn–Ta–Nb deposit (located in Galicia, Spain) via hydrometallurgical route [1,2]. The recovered oxides have been used to obtain micro- and nanostructures by a simple thermal evaporation method. The structures have been characterized by means of X-ray diffraction, scanning electron microscopy, luminescence and Raman spectroscopy. The possibility of using these micro- and nanostructures for optical, sensing and energy storage applications will be discussed and related to the crystal structure of the oxides obtained [3,4].

Defect reduction through modelling plastic deformation and metallurgical evolution in ferritic stainless steels.
Submitted: 17 Dec 2020
Abstract: Show Abstract
Flat products made of EN 1.4512 ferritic steel may present some defects after the hot rolling process, such as irregular jagged edges. In order to identify the origin of this type of defect to help their reduction, a study has been carried out considering the hot rolling conditions of flat bars made of EN 1.4512 steel. Many semi-empirical models regarding the microstructural evolution during hot deformation of austenitic stainless steels have been developed by many authors. On the contrary, no many studies have been performed about ferritic stainless steels. The main novelty of this work is in the development of a recrystallization and grain growth model applied to EN 1.4512 ferritic steel grade. The microstructural evolution of the ferritic grain size and the damage of the material were calculated through the coupling of metallurgical and damage models. In the thermomechanical simulations of the roughing passes, three granulometry levels (PFGS) and three heating furnace temperatures were considered. The ferritic grain evolution metallurgical model was obtained introducing adequate equations. The results show that the defect can be produced by process conditions that trigger abnormal heating which induces an uncontrolled growth of the grain on the edges. The work-hardened grains undergo elongation during hot deformation but are not able to recrystallize. Consequently, these grains “squeezes” the surrounding recrystallized matrix towards the edges of the bar. Thus, on the edges occurs fractures that macroscopically manifest themselves as jagged edges.
Microstructural and thermomechanical simulation of the additive manufacturing process in 316L austenitic stainless steel

Abstract: Show Abstract
|, , , , ,||N/A||
Controlling the microstructural evolution generated under Additive Manufacturing (AM) conditions is a key aspect to achieving the target mechanical properties. In the present study, an integrated thermomechanical and microstructural simulation of ΑΜ, as applied to an AISI 316L austenitic stainless steel, is presented. A one-way coupled analysis is carried out with the heat transfer, microstructural and mechanical problems solved in sequence. A ﬁnite element technique is employed to evaluate the temperature evolution as well as residual stresses and distortions in the processed part, due to the successive material deposition. The material deposition is modelled using quiet elements which are activated as the added material solidifies. These elements are present from the start of the analysis but are assigned properties so they do not affect the analysis. The thermal history generated by two-dimensional heat transfer simulations which is essential in determining the resulting microstructure. The effect of processing parameters on critical microstructural features such as freezing range, phase fractions, and elemental segregation were investigated via CALPHAD-based computational thermodynamic and kinetic modelling, implemented in the Thermo-Calc software. Two limit cases of equilibrium and instantaneous solidification were studied through thermodynamic calculations and the Scheil-Gulliver model. Kinetic analysis followed, using the complete thermal cycle calculated by heat transfer simulations. Solidification and solid-phase transformations were investigated upon thermal cycling via multi-phase and multi-component diffusion simulations. A distinction between eutectic and peritectic solidification modes was made, as both have been observed in AM studies. Model comparison carried out, in agreement with experimental observations, indicated that the peritectic diffusion model resulted to the highest freezing range and the smallest ferrite fraction. The ensuing microstructural properties, including phase fractions and constitutions, as well as the temperature field are provided as an input for a mechanical analysis, to calculate the residual stresses and distortions.
Bubble Behavior on Horizontal and Vertical Carbon Anode Surfaces in Cryolite Melt Applying a See-Through Cell
Submitted: 10 Dec 2020
Abstract: Show Abstract
Gas bubble behavior on a carbon anode in a cryolite melt have been studied by direct observation using a see-through cell. The bubble phenomena studied have been growth, coalescence and detachment during electrolysis. The anode geometry and surface orientation affect bubbles behavior. Therefore, two different anodes were tested, an anode with a horizontal facing-downwards surface and an anode with a vertical surface. Galvanostatic and potentiostatic measurements were performed for different current densities and different potentials with simultaneous video recording. At the horizontal anode for a constant current density/potential it was found that one large bubble was formed by growth and coalescence of smaller bubbles and finally the large bubble detached periodically. The frequency of the bubble release events observed from the video recordings was in agreement with the dominant frequency from the Fast Fourier Transform (FFT) analysis. For the vertical anode surface smaller bubbles were formed and detached either due to being pushed by the formation of other bubbles or by coalescence obtaining enough buoyancy. FFT analysis gave no dominant frequency. The diameter of detached bubbles from the horizontal surface and vertical surface was measured. The value was in a range 5.7 mm to 7.2 mm for the horizontal surface and in a range 1.5 mm to 3.7 mm for the vertical surface, strongly depending on the applied current density. The bubble diameter was decreasing with increasing current density for both surfaces. The smaller bubble diameter might be explained by a larger bubble induced convection and increased wetting.
