United Approach to Modelling of the Hot Deformation Behavior, Fracture, and Microstructure Evolution of Austenitic Stainless AISI 316Ti Steel

Hot deformation is one of the main technological stages products made from metallic materials. It strictly required to decrease costs developing optimized technologies at this stage without a significant in products’ quality. The present investigation offers an algorithm unite three different models predict hot behavior, fracture, and microstructure evolution. compression tension tests AISI 316Ti steel were conducted using thermomechanical simulator Gleeble 3800 for models’ construction. strain-compensated constitutive model Johnson–Mehl–Avrami–Kolmogorov (JMAK)-type grain structure evolution show satisfactory accuracy 4.38% 6.9%, respectively. critical values modified Rice Tracy fracture criteria determined experimental relative cross-section reduction finite element calculation stress triaxiality. developed approved stainless by torsion with test.
