The Various Precipitate Phases in Stainless Steels

Pp. 90-110 (21)

Joseph Ki Leuk Lai, Kin Ho Lo and Chan Hung Shek

Abstract

This chapter gives an overview of the various precipitate phases that can form in the different classes of stainless steels. Besides the phases that are well-studied, a newly discovered phase, called the J phase, is also introduced. The conditions under which the different phases will form, the problems they cause, the methods for alleviating these problems, and the new methods for the detection of the various phases are presented.

Keywords:

Sigma phase, chi phase, martensite, carbide, J phase, G phase, Z phase, electron domain, S phase, spinodal decomposition, 475°C embrittlement, austenite, ferrite, intermetallic, sensitization.
