Abstract

This chapter examines the effect of heat treating and other processes on the microstructure-property relationships that occur in superalloys. It discusses precipitation and grain-boundary hardening and how they influence the phases, structures, and properties of various alloys. It explains how the delta phase, which is used to control grain size in IN-718, improves strength and prevents stress-rupture embrittlement. It describes heat treatments for different product forms, discusses the effect of tramp elements on grain-boundary ductility, and explains how section size and test location influence measured properties. It also provides information and data on the physical and mechanical properties of superalloys, particularly tensile strength, creep-rupture, fatigue, and fracture, and discusses related factors such as directionality, porosity, orientation, elongation, and the effect of coating and welding processes.
