Abstract
High-temperature high-cycle fatigue properties until 107 or 109 cycles of nickel based superalloy Alloy713C were investigated at 600, 700 and 800°C. For Alloy713C as casting, fatigue fracture originated from casting defects in high-cycle region. While for Alloy713C treated by hot isostatic pressing (HIP) , fatigue fracture originated from the specimen surface. In high-cycle region, fatigue life of Alloy713C treated by HIP was longer than that of Alloy713C as casting.
