Evaluation of the softening mechanisms of AISI 4340 structural steel using hot torsion test

We performed double hot torsion deformation tests on structural steel SAE 4340. The test temperature and strain rate were kept constant at 1050 °C and 0.2 s-1, respectively; while the applied strain (0.2 and 0.4) and the time between passes (1 s, 5 s and 40 s) were varied. The samples were heated to...
