Sažetak
Stress-relief Heat Treatment (HT) is an important procedure used to reduce the residual material stresses that occurred during various manufacturing processes. During the HT procedure, a metallic material is subjected to controlled time-temperature cycle. This cycle typically consists of several phases: heating the structure to required temperature below the transformation temperature A1, holding it at stress relieving temperature until the structure is homogeneously heated, and finally cooling it down slowly to environmental temperature. In multi-material structures that require HT, the thermal influence on all materials must be determined and considered. Wear-resistant steel for structural purposes, with high strength and hardness in delivered condition, is sensitive to subsequent heating in excess of 250 °C, and therefore generally not intended for HT. This paper aims to experimentally investigate influence of HT on general mechanical properties of Hardox 450. This is necessary to gain further insight into HT and residual stresses correlation, and to create valid material model for numerical simulations.
