Abstract

Alloy 625 is designed as a solid-solution alloy. Still, it develops a highly complex microstructure when different intermetallic phases and various carbides precipitate in the austenite matrix during processing and heat treatments. The precipitation of these phases modifies the alloy’s behavior depending upon their nature, morphology and location of formation. This chapter gives an overview of the alloy's chemistry and its phase transformation behavior and describes how the microstructure is modified when these phases evolve.
