Abstract:
During the thermal processes in metallurgy, it is important in many cases to know the exactly particularities of heat transfer in a complex system. In the case of steel semi-finished products heating, the most of the models refers to the heat exchange by convection and radiation or to the heat transfer by conductivity inside the material. [..]

Abstract:
The effect of preliminary heat treatment and equal channel angular pressing in step die on the microstructure and properties of steel grade 45 are analyzed. There is revealed that the grain size after equal channel angular pressing depends little on the preliminary heat treatment, however, annealing reduces the hardness of steel, which helps to reduce the effort of pressing on the first passes.

Abstract:
The aim of this paper is to determine the impact of heat treatment of steel pre-treated thermo-mechanically using Gleeble 3800 simulator on the structure and mechanical properties of investigated high-manganese austenite Fe-Mn-(Al, Si) steel, containing 25% of Mn, 3% of Si, and 3% of Al. Applying thermo-mechanical treatment using Gleeble 3800 simulator allow to obtain the conditions for a gradual grain refinement controlled mainly by dynamic recrystallization and also by a dynamic recovery in a whole temperature deformation range.

Abstract:
The paper is aimed on appraisal of influence of preceding deformation on spring steel CCT diagrams, which were created on the basis on dilatometric analyses of cooling curves, using universal plastometer Gleeble 3800, CCT and DCCT diagrams after austenitisation at the temperature of 850 °C, which were further supported by metallographic analyses and hardness measurements HV30. Dilatometric tests were performed at different cooling rates in the range from 0.16 to 12 °C/s. [..]

Abstract:
Uniaxial hot compression tests performed on a HDS-20 Hot Deformation Simulator were utilized to compare the influence of niobium amount on hot flow stresses of these steels. For both steels, the temperature range from 700 °C to 1200 °C in combination with the nominal strain rate range from 0.1 s-1 to 100 s-1 were investigated. [..]
