Fig.1. Fatigue life is enhanced by introducing the metastable austenite structure (TRIP—transformation induced plasticity steel, DP—dual phase steel, F-B-M (R)—steel contains ferrite bainite martensite and retained austenite, T-M (F)—steel consists of tempered martensite)[41,42] (a) and the introduction of the metastable austenite structure reduces the fatigue life[43] (b)
