Effects of cold-working and annealing at 700 °C on hardness of 08Ch18N10T steel

Popis výsledku v původním jazyce

Rectangular specimens made of austenitic stainless steel 08Ch18N10T were cold-pressed to different levels of thickness reduction in order to induce various work-hardening in the material. Hardness was measured on each specimen to study its dependence on the level of work-hardening pre- and post-annealing at 700 °C. The dependence of hardness on the time spent in furnace was also studied to better understand anomalous behavior of this material when annealed at 700 °C. The results of this study are in line with previous studies and show that the decrease of hardness of work-hardened specimens when annealed at 700 °C is smaller than when annealed at different temperatures in range 550-900 °C. The experimental work was accompanied by numerical simulations using the finite element method (FEM). The numerical simulations are used to select an optimal place on the surface of the annealed specimen for hardness measurements to achieve consistent results.
