Decoupling the Impacts of Strain Rate and Temperature on TRIP in a Q&P Steel

Abstract The individual effects of strain rate and temperature on the hardening a quenched partitioned steel have been examined. During quasistatic tests, resistive heating was used to simulate deformation-induced that occurs during high-strain-rate deformation, while martensitic transformation tracked by combination x-ray electron backscatter diffraction. Unique work rates under various thermal–mechanical conditions are discussed, based balance between concurrent dislocation slip transformation-induced plasticity deformation mechanisms. diffraction data suggest imposed exhibited dissonant influences phase transformation.
