The 32nd International Conference on Metallurgy and Materials METAL 2023 took place in Brno on 17-19 May 2023. Almost 180 participants from 21 countries listened to 65 lectures and viewed 86 posters.

The conference was opened by Assoc. Prof. Christian Bernhard, a head of a steel cleanness and casting research group in Department for Metallurgy, Montanuniversität Leoben, Austria. He dedicated his lecture to the topic of Continuous Casting of Steel: Latest achievements and future challenges for research. The second plenary lecture was given by Jožef Medved, professor at the Department for Materials and Metallurgy, Faculty for Natural Science and Engineering, University of Ljubljana, Slovenia. The lecture dealt with the Aluminium – Sustainable Material of Green Transition.

However, the thematic scope of the conference lectures was traditionally much broader. Researchers presented innovations not only in the fields of advanced iron, cast iron, steelmaking, non-ferrous metals and alloys, metal forming and surface engineering, but also in the economics and management of metallurgical production.

The prize for the best poster has been awarded to Alexandr Arbuz from Nazarbayev University in Temirtau (Kazakhstan). In his work, he presented FEM-Simulation of Transverse Defect Closure in Austenitic Stainless Steel by Radial Shear Rolling.

The Czech Association of Scientific and Technical Societies awards the prize for the best poster presentation in the student category to Zuzana Košelová from Institute of Scientific Instruments of the CAS, Czech Republic, for her poster on Functional Tungsten-Based Thin Films and Their Characterization.

The next 33rd METAL conference will take place on May 22 - 24, 2023.

Abstract: The main topic discussed in this work is the reduction of hydrogen content in high grades of steel for the production of seamless pipes using processes of secondary metallurgy and vacuum degassing. The aim of thispaper is the statistical analysis of operational data with a follow-up to the preparation of a statistical model for calculating the final hydrogen content in steel after processing in a vacuum.

Abstract: During recrystallisation annealing after cold forming, it has been repeatedly observed that there is a critical range of strains beyond which enormous coarsening of the statically recrystallized grain occurs. It can be assumed that similar behaviour can also be expected during hot rolling with static recrystallisation (SRX) between passes, especially in the first passes at the highest temperatures.

Abstract: Hot forging processes are influenced by numerous thermo-mechanical-metallurgical material phenomena, which interact strongly. In particular, the strains due to transformation-induced plasticity (TRIP) occurring during the forming process have a considerable influence on the distortion and residual stresses of the components.

Abstract: By cold forming metastable austenitic steels below 0 °C, the strength is increased significantly through martensite phase transformation in addition to strain hardening. This deformation-induced effect enables the use of corrosion-resistant materials for highly loaded applications such as bearings under oxidative atmospheres, where the use of conventional corrosion-prone steels is unsuitable.

Abstract: Hybrid components are made by combining two or more different materials and used in applications where monolithic components are not suitable due to their limited functionality or performance. Combining steel and aluminium in a technical component for power transmission provides the advantages of locally improved strength and reduced weight. [..] Read more

Abstract: One of the most important parameters used for qualitative evaluation of lubricants in cold drawing of steel wires is the coefficient of friction. Its magnitude cannot be determined directly, but it can be determined from the measured total drawing force (TDF) or total drawing torque (TDT). [..] Read more

Abstract: The process of closing defects in 12% Cr austenitic stainless steel by radial shear rolling on an RSP 10-30 mill was investigated. The advantage of radial shear rolling over other rolling methods is that it is an efficient way of achieving a high monotonic uniform deformation of the steel. [..] Read more

Abstract: The paper concerns the evaluation of the formability of sheet metal by means of the cylindrical cup drawing test, which belongs to the imitation tests of the formability of sheet metal, and the influence of individual factors on the results of drawing. Experimental drawing of cylindrical stampings from a set of blanks from Cu-ETP (also known as conductive copper) sheet with a circular element deformation network was carried out using a special jig in the Department of Mechanical Technology, Faculty of Mechanical Engineering, VSB - Technical University Ostrava.

Abstract: During the pressing of sheet metal parts, cracks may form around the holes that weren't predicted by numerical simulations. These cracks are caused by the partial depletion of the forming capacity at the edges of the hole due to the preparation technology used, most often shearing. [..] Read more
