Measurement of prior austenite grain size was in reasonable agreement of the size calculated for the time and temperature that the steel was held prior to quenching (Table 2).
The relatively lower wear of the SS-CrC type hardfacings, stress-induced martensitic transformation of the retained austenite, which happens during the wear test [28], may be suggested as the most probable cause.
To measure the volume deduction of the retained austenite according to the ASTM E975 standard, X-ray and X'pert HighScore Plus software were used [5].

The first two, with [M.sub.s] smaller than Mf, indicate the temperatures at which the transformation of austenite to martensite starts and finishes during cooling.
In fact, actually, the austenite phase is metastable at room temperature and becomes unstable when an external mechanical or thermal energy is introduced.
Retained austenite in the final microstructure of advanced steels is an important phase which provides a combination of strength and ductility.
This results in a microstructure of lightly tempered martensite, primary carbides, and up to 12-17% retained austenite.
