Experimental Research of Strain of Material 12CrlMoV under the Conditions of Normal Temperature and Mesothermal Temperature

摘要

In this paper, a universal material testing machine is used. The step stress tensile tests are carried out and strain of material 12CrlMoV is measured by different modes of connection. The specimen is heated through a heating unit and mesothermal tensile experiments are put. Strain and temperature are measured at the same time. Lots of experimental data are acquired and analyzed. Some beneficial conclusions are drawn.
