Abstract:

16MnR steel is a most widely used material for pressure vessels.The study on fatigue is very important for safety and fatigue life assessment of pressure vessels.Several experimental researches for fatigue of 16MnR steel were conducted and test data have been gotten,but it was short of fatigue study of the material under various conditions at present.The fatigue crack growth tests of 16MnR hot-rolling steel were carried out at different temperatures and R-ratios with compact tension(CT) specimens in this pa...
