  • The notch effect on the fatigue strength of 51CrV4Mo spring steel = Vpliv zareze na trajno nihajno trdnost vzmetnega jekla 51CrV4Mo
    Šuštaršič, Borivoj ...
    Standardized and technological testing of the fatigue strength of spring steels is a complex and time-consuming, and therefore expensive, task. The determination of Woehler's (S-N) curves using a ... resonant pulsator is relatively fast and simple. In this investigation the test is performed using standard Charpy V-notched specimens with the aim to obtain an appropriate comparison with the results of technological tests on real springs. The steel springs were made of high-quality flat steel with a smooth shot-peened surface, free of notches and with no large microstructure or surface defects. The performed investigation can help with quality control and improvements to the properties of the steel springs. The paper presents determination of the fatigue strength of 51CrV4Mo spring steel using a resonant pulsator. The notch effect, the influence of the microstructure and the surface quality are also discussed.
