【Abstract】 Thermal ratcheting test were performed on 306 stainless steel cylinder specimen at 300 ℃ under static tension and cyclic torsion loading with MTS 809 electro-hydraulic servo controlled materials testing system and the furnace designed by the authors. The test method for simulating thermal ratcheting was established. The test results show that the method is not only easy to use and accurate to control, but also very useful to engineering design of the pressure vessels subjected to transients.更多还原
