Abstract

The strengthening phases in a ultra-high strength stainless gear(bearing) steel have been investigated by TEM electronic micrographs and diffraction techniques.The results show that two types of hcp phases:Laves(Fe2Mo type) and M2C have been precipited in coherence with martensitic matrix during tempering and both of them may be ascribed to the existence of secondary hardening phenomenon in the steel.

Key words
