Testing Design of Low Stress Loading of Compression Module on Gleeble-3800 Thermal Simulation Testing Machine

A low stress loading test was designed based on single axial compression module on Gleeble-3800 thermal simulation test machine. The test scheme overcame the instability problem of low stress control of the Gleeble-3800 compression module, and realized the single-axial low stress loading under the fixed temperature, and the loading force was maintained between -200 N and -500 N. Through this test, the process of the bainite transformation could be measured under the condition of single-axial low stress loading at the same time. The test scheme provided a solution for the study of bainite transformation process under the low stress loading on the Gleeble-3800 thermal simulation test machine.
