THE SENSITIVITY OF 42SiCr STEEL TO INCLUSIONS UNDER FATIGUE LOADING FOR THREE DIFFERENT WAYS OF HEAT TREATMENT
Result description
The aim of this work was the interpretation of results of fatigue tests of low alloy 42SiCr steel. Three different types of heat treatment conditions were compared: (i) as received hot rolled material, (ii) classically heat treated material (quenched andtempered) and (iii) heat treated material using advanced quenching and partitioning (Q-P) process. The results of fatigue tests in combination with fractographical analysis showed significant differences concerning effects of inclusions on fatigue crackinitiation evaluated as a dependence on the type of heat treatment of the samples. The influence of inclusions was evaluated by Murakami´s model (Murakami and Endo, 1994 [1]). This influence was compared with the difference of real fatigue life and expected fatigue life from Wöhler curve.
