Investigation of Low-cycle Fatigue Behavior on Candidate Alloy C263 for A-U.S.C Boiler
This study firstly got the full range uniaxial constitutive relationship by uniaxial tensile tests, based on FAT (finite element auxiliary test) method, up to failure on candidate alloy C263 for A-U.S.C boiler at room temperature,700℃ and 730℃ , respectively, which can be applied as basic data for large deformation analysis.A series of low cycle fatigue tests under strain controlling on the alloy at three temperatures had been carried out, some key mechanical properties such as Mason-Coffin model for life prediction and cyclic constitutive cures were given.Results of tests showed that tensile properties oftbe alloy at room temperature are better than those at elevated temperatures and there is little difference between 700℃ and 730℃.The alloy behaves obvious cyclic-hardening during low cycle fatigue tests at three temperatures, and fatigue-life is reduced as temperature is increased.
