In this investigation of AISI 1045 steel are tested in two stages. the first stage samples, induction boriding and hardening heat treatment typically 800 °C, 900 1000 1100 1200 °C applied over course seconds. Internal strains maybe mitigated using a 30 min tempering at temperature ranges 300 500 °Cand 700 °C. After that samples subjected to hardening, microhardness tensile strength according AS...
