Sažetak
This article describes investigations into the existence of correlation between experimentally determined cyclic parameters and hardness of quenched and tempered representative low alloy steel 42CrMo4. A good correlation was found to exist between cyclic strength coefficient K' and Brinell hardness HB, but not between cyclic strain hardening exponent n' and hardness HB. Nevertheless, good agreement between calculated and experimental cyclic stress-strain curves shows that cyclic parameters i.e. cyclic stress strain curves of the investigated steel can be successfully estimated from its hardness.
