TOOLS MATERIAL BEHAVIOR AT ELEVATED TEMPERATURES

In this paper experimental data related to material mechanical properties as well as material behavior at elevated temperatures are obtained. Tensile tests at different elevated temperatures are carried out and also for some of these temperatures one-dimensional short time creep tests for different constant loads are made. Experiments are made using modern computer controlled 400 kN materials testing machine equipped by high temperature furnace and the corresponding high temperature extensometer. Some of material creep responses are also numerically modeled. The curves of mechanical properties and creep responses, engineering stress-strain diagrams, as well as curves of specimen's elongation and reduction in area are also presented.
