Resum
Simulations of thermomechanical processing of a high niobium- and nitrogen-bearing austenitic stainless steel for orthopedic implants (ISO 5832-9) were conducted using hot torsion test with multiple deformations under continuous cooling conditions. Samples were reheated to 1250 °C and subjected to deformation schedules with pass strain of 0.3, strain rate of 1 s- 1 and interpass times of 5, 20 and 50 s. Optical microscopy, TEM, EDS and EBSD were used to characterize the samples. Characterizatio...
