... Cast austenitic stainless steel 1.4848 is used to manufacture automotive exhaust system components. Low cycle fatigue (LCF) of 1.4848 austenitic steel was investigated through strain controlled fatigue testing at strain rates of 0.02/s, 0.002/s, and 0.0002/s in the temperature range from room...

.... Thus, materials were first tested under low cycle fatigue (LCF) deformation routes. LCF tests showed that the differences observed in the number of cycles to failure between alloys are mainly a function of the differences in fracture toughness. Fractography of the fatigue and toughness tests samples...
