摘要：

9 Cr-1 Mo steel is gaining importance as a construction material in fast breeder reactors and thermal power plants, where good high-temperature performance is required. It shows good high-temperature creep and corrosion resistance. In its applications the steel is subjected to a variety of stresses, thermal fatigue, creep and used with a minimum life expectancy of about 30 years. Under suitable conditions of microstructure, strain rate and temperature, the steel exhibits extensive dynamic strain aging. The investigation reported is an analysis of this post yield deformation mode. Some typical engineering stress-strain curves are presented.
