The use of different mathematics models to calculate the residual stresses generated during the nitriding process, Daves and Fischer (1993), Schreiber et al. (1993), Amariei et al. (1997), implies, among others, the knowledge of creep behavior for the nitrided steel. Because the steels for nitriding are not commonly used in conditions of stresses at high temperatures the experimental data base
... [Show full abstract] presented until now is insufficient in what concerns the steel creep. The paper presents the functions of the creep families of curves at 500°C and 550 °C for 38 MoCrAl 09 steel. The experimental data were processed using an original methodology, briefly presented in as follows.
