註釋Tension and torsion low-cycle fatigue tests were carried out on thin tubular specimens of 316 stainless steel, tested at both room temperature and 600°C. Two types of experiments were performed: (1) conventional continuous isothermal tests, and (2) isothermal sequential tests with different sequences of tension/compression and torsional loading. Most of these tests were carried out under air environment at the equivalent total strain amplitude of ??t/2 = ±0.80% in tension or ??t/2 = ±0.80 ?3% in torsion. Optical and scanning electron microscopy were used to analyze the failure modes, the orientation of microcracks and macrocracks which lead to failure, and crack density.
