Nonisothermic cyclic deformation of $12\rm Cr18\rm Ni10\rm Ti$ steel under high temperatures

The paper formulates the fundamentals and basic equations of the thermoplasticity theory. It presents material functions to close the thermoplasticity theory for the $12\rm Cr18\rm Ni10\rm Ti$ steel at high temperatures. It analyzes the simulation and experimental results of subjecting the $12\rm Cr18\rm Ni10\rm Ti$ steel to strain-controlled cyclic deformation by isothermal and non-isothermal high-temperature loading until the specimens break down. The subject matter of analysis is the range of in-cycle stress values as induced by non-isothermal cyclic loading. Computational and experimental results fit reliably.
