Influence of shot peening parameters on high-cycle fatigue strength of steel
What is it about?
Our present article is focused on effect of shot peening parameters on fatigue strength of steel manufactured by PM. Steel material had been produced by powder metallurgy process.
Why is it important?
Shot peened samples were peened by different peening intensity, 100% and 200% saturation and full coverage conditions. Fatigue performance of steel produced by PM process improved by surface peening process. For the studied PM steel best fatigue performance was obtained with the samples that shot peened by 20 A intensity and 100% saturation. Fatigue strength and endurance limits of the samples reduced after a certain cold work level. Higher intensity and saturation levels of peening process deteriorated the beneficial effect on fatigue strength and fatigue endurance limit.
