Abstract:
The practical aim of the following study was to develop a new roll pass design (RPD) of the channels (UPN) and introduce it into industrial rolling. The necessity of usage of a charge stock with a greater cross section has caused necessity of an application of the new rolling schedule characterized by large deformations. [..]

Abstract:
The approach of the most common industry-specific FE-systems for the service life evaluation of forming tools holds some disadvantages. For example, within the decoupled tool analysis, load situations are typically analysed at room temperature and thus, the transient temperature development in the forging die is not considered in the lifetime evaluation.

Abstract:
The main goal of this study is to analyze the influence of radial-shear rolling (RSR) modes on the structure and properties of 1050A using finite element modeling (FEM) and experimental verification of the results. Ingots with a diameter of 60 mm were obtained, which were rolled into rods with a diameter of 14 mm at different regimes (total elongation ratio µ = 18.4). [..]

Abstract:
Development of technologies to produce the very fine structure is currently very intensively accelerated. Even in scientific research, it is recognized that precisely controlled forming processes, including special processes, enabling control of technological parameters with regard to the structure refinement, and tied with the strengthening of materials, currently had the highest gradient of utilization efficiency of the scientific research findings in practice.

Abstract:
In this article a continuous severe plastic deformation (SPD) process entitled dual rolls equal channel extrusion (DRECE) for producing ultrafine-grained (UFG) microstructure of thin sheets is presented. The DRECE process combines conventional equal channel angular pressing (ECAP) process and continual CONFORM process, and it can be easily scaled for industrial use. [..]

Abstract:
Low-alloy steel 16Mo3 is often used for tubes and other components of the pressure system of a boiler operating at elevated temperature (up to 530 °C). Long-term exposure of low-alloy steel components at elevated temperatures inevitably result in some kind of structural degradation; for example, creep cavitation, carbide coarsening and/or spheroidization, and, less commonly, also graphitization.

Abstract:
During resistance welding, the electrode tips are significantly worn. The amount of wear is strongly dependent on the welded material, the surface treatment of the welded sheet, the thickness of the surface treatment, the welding parameters and, last but not least, especially on the number of performed welds.

The combination of different mechanical properties of tailor welded blanks (TWB-s) results in non-constant plastic flow and instability of the weld interface during forming. This is most marked when combining metal sheets of different thicknesses or sheets with significantly different plastic characteristics. [..]
