Abstract
The enhancement of the strength of a metastable austenitic AISI 304 L-type stainless steel by fatigue-induced martensite formation in the temperature range 103 K to 298 K was investigated. The fatigue tests were run in closed-loop plastic strain control using a symmetric sinusoidal wave form (0.2 Hz). Plastic strain amplitudes were in the range 3.2×10-3 to 1.26×10-2. The increase in strength caused by fatigue-induced martensite formation was measured by subsequent monotonic tensile tests at room temperature. The fatigue-induced martensite content and, as a consequence, the increase in strength and the residual fatigue life vary strongly with pre-deformation conditions (plastic strain range, test temperature, number of cycles). The cyclic pre-deformation conditions can be optimized to achieve the best combination of strength and residual fatigue life as required for technical applications.
