High Cycle Fatigue Properties of Hot-rolled TC1 and TC2 Titanium Alloys
Through performing the stress-controlled fatigue tests,the high-cycle fatigue properties of hot-rolled TC1 and TC2 titanium alloy plates at different testing temperature were investigated,and the fatigue properties of two alloy plates were compared.The results show that,at the same maximum cyclic stress,the fatigue lives of both TC1 and TC2 alloy plates decrease with the increase of temperature.At the same testing temperature,the fatigue life of TC2 alloy plate is longer than that of TC1 alloy plate.In addition,both TC1 and TC2 alloy plates show lower fatigue limit at higher testing temperature.At different temperature,the fatigue limit of TC2 alloy plate is higher than that of TC1 alloy plate.
