Effect of Elevated Temperatures on Behavior of Structural Steel 50CrMo4

In this paper an effect of different temperatures on mechanical properties and creep responses of 50CrMo4 steel were considered. Both mechanical properties and creep behavior were determined by uniaxial tests. Curves representing specimen elongations as well as reduction in specimen areas at elevated temperatures are also shown. Creep curves as the responses of the considered material subjected to uniaxial stresses at high temperatures are also demonstrated. The notch impact test was carried out using Charpy impact machine and fracture toughness was calculated. The experimentally obtained data may be of significant interest in structure design procedure.
