abstract = "The effects of cast and heat treatment processes on microstructure and mechanical property of K4169 alloy have been investigated. The results show that low shell and pouring temperature can significantly improve the room temperature tensile and elevated temperature stress-rupture properties of the alloy; The joint function of hot isostatic pressing (HIP) and homogenization+solution+aging (HSA)standard heat treatment can effectively close casting defects such as micro-looseness, significantly improve the segregation of the alloy structure, basically eliminate the Laves phase, only a small amount of MC carbide dispersed in the grain boundary and short rod-shaped δ-phase. What is the most significant is that a large number of lenticular γ'' phases are uniformly precipitated, which enhance the microstructural stability, and significantly improve the room temperature tensile properties and high temperature endurance properties of K4169 alloy.",
