Abstract:
High strength properties and a wide range of deformation hardening, particularly in case of dynamic deformation, enable application of manganese steels in the structure of highly strained elements constituting mechanical vehicle framework. This is true primarily for railway, automotive and military industries, where not only decrease in weight, but also safety improvements are of importance. [..]

Abstract:
Deformation characteristics of carbon steel are studied in the temperature range 900 - 1200 °C and strain rates 0.1 - 100 s-1 on the plastometr Gleeble using compression tests on cylindrical samples. Processed a single dissipation maps in the field of forming are developed on the basis of changes in the effectiveness of dissipation, depending on temperature and deformation resistance, taking into account the strain rate.

Abstract:
Transformation kinetics of austenite during cooling is influenced by several factors as chemical content or thermomechanical parameters (temperature, dwell time, deformation, strain rate, cooling rate) and initial structure state, consequently initial austenite grain size. The aim of this article was just to assess the effect of initial structure state (casted, deformed, purposely extremely coarsened) on transformation kinetics of austenite during cooling of steel C10, which was moreover deformed uniaxial compression.

Abstract:
In this study, the evolution of some properties of the wire drawn alloy AGS 6101 will be followed and the effect of a heat treatment at high temperature will be analyzed.OM (optical microscopy) and SEM (scanning electron microscopy) observations showed an homogeneous fibrous microstructure in the longitudinal cross-section. However, the EBSD (electron backscatter diffraction) analysis showed that the distribution of the two main crystallographic fibers <111> and <001> was not homogeneous through the cross-section of the wire.

Abstract:
The hot deformation behaviour of Ni55Cr45 alloy was investigated by isothermal compression test on the GLEEBLE 3800 thermo-mechanical simulator in the wide range of temperatures (750 – 1150 °C ) and strain rates (1 – 100 s-1). The experimental stress-strain data were employed to develop the constitutive equation and activation energy of the investigated Ni-Cr alloy. [..]

Abstract:
Indefinite chill cast iron rolls are commonly used in the finishing stands in hot strip rolling mills. Due to characteristic rolling conditions in these stands and due to a hypoeutectic ledeburitic microstructure with graphite inclusions in the working layer, the mechanism of thermo-mechanical wear is different from earlier stands.
