TENSILE TESTING OF MATERIALS AT ELEVATED TEMPERATURES ON A SMALL LABORATORY DEVICE

Abstract

Machine parts and constructions are often exposed to elevated or high temperatures in their working environment. The mechanical characteristics of metals obtained by tensile testing then change, so it is very important to know their properties under such conditions. Reliable and accurate values of the mechanical characteristics of metals can be obtained by tensile testing on a small laboratory device. By developing a simple and cost-effective module for testing metals at elevated and high temperatures, experimental tests of DC01 steel were performed at temperatures up to 600 °C, and the results were verified with the results available in the literature. The obtained values of the mechanical characteristics of the materials tested on a small laboratory tensile testing device are in accordance with the results obtained on a conventional tensile testing device.
