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. [..]

DOI: https://doi.org/10.37904/metal.2023.4639, 164-169
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.

DOI: https://doi.org/10.37904/metal.2023.4634, 170-174
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. [..]

Abstract:
Copper is a very popular electro-conductive material, however, the mechanical properties of pure Cu are low. They can be typically improved by (micro)alloying, or via structure modifications introduced by optimized deformation and thermomechanical treatments. [..]

Abstract:
The AISI 316L stainless steel is one of the most used 3D printed powder materials due to its good properties. It goes without saying that the properties of the 3D printed steel are naturally less or more different compared to the material which was prepared conventionally. [..]

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). [..]

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. [..]

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:
Equal-channel angular pressing (ECAP) is one of the main ways of refinement the structure of metals into a fine-grained and nanostructured state. Regardless the great prevalence and high knowledge of the method, the issues of optimization and improvement of the design and geometry of the working tool still relevant. [..]

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. [..]
