Parameters affecting low-cycle fatigue life of AlSl 304, 316, and 348 were investigated. Test parameters were temperature, strain amplitude, strain rate, and length of hold times at peak strain in each cycle. Metallographic and fractographic analysis of 348 and 304 stainless tested at 650 and 816 deg C and strain rates of 4 x 10{sup -3}, 4 x 10{sup -4} and 4 x 10{sup -5} sec{sup -1} showed that the mode of crack initiation was intergranular for all conditions except for the highest strain rate at 650 deg C. At these conditions, the 304 exhibited a transgranular type crack initiated at the highest and lowest strain range evaluated. The 348 exhibited better strain fatigue resistance for a given total axial or plastic strain level. Fatigue resistance at 316 to 650 deg C is less than 304 or 348. The 316 exhibited strain hardening followed by softening over the entire range (F.S.)
