Microstructure mechanism, cyclic deformation behavior of an Fe-Ni-Cr alloy considering non-Masing behavior

The non-Masing behavior of Sanicro 25 alloy was studied during high-temperature low-cycle fatigue (700 °C). The results showed that Sanicro 25 alloy exhibits the non-Masing behavior when total strain amplitude (εa) increased. The analysis of stable hysteresis loops showed that the stress amplitude (σa) increased with increasing εa. At the stable cyclic stage, the rate of increase in σa with number of cycles increased when εa increased. Based on...
