| Abstract | We report a method, named as T & A treatment, to improve the high-cycle fatigue (HCF) property of twinning-induced plasticity (TWIP) steel without sacrificing its ductility and work-hardening ability. A long-range gradient in grain size was obtained in the TWIP steel, whose HCF resistance is better than both coarse-grain and fine-grain steels, breaking the rule of mixture. The surprising HCF property of the graded grain structure is believed to originate from the large generation of geometrically necessary dislocations and the formation of hard core and soft shell construction during cyclic loading. IMPACT STATEMENTA new strategy, refers to long-range gradient in grain size, is proposed to improve the HCF property of TWIP steel. The graded structure exhibits better fatigue resistance than single unit. [GRAPHICS] |
