An approach to lifetime prediction for a wrought Ni-base alloy under thermo-mechanical fatigue with various phase angles between temperature and mechanical strain
Source abstract
Abstract
Abstract The damage and lifetime behaviour of Ni-base alloy NiCr22Co12Mo9 (comparable to Inconel Alloy 617) under thermo-mechanical fatigue (TMF) loading with varying phase angles between strain and temperature and optional dwell times at the maximum temperature was studied. Based on the results, a new lifetime prediction approach is proposed. Strain controlled TMF tests with a temperature range of 100–850 °C were conducted in air. Phase angles between temperature and mechanical strain were 0° (in-phase, IP), 180° (out-of-phase, OP), +90° (clockwise diamond, CD) and −90° (counter clockwise diamond, CCD). In some tests, optional dwell times of 2, 5 or 30 min were introduced at 850 °C. The TMF-lifetime depends significantly on the phase angle and increases in the sequence IP
