Conclusions
-
1.
The resistance to abrasive wear is high for chromium steels with unstable austenite, which transforms to martensite under the influence of abrasive particles. The wear resistance of such steels depends on the rate of the γ → α transformation.
-
2.
For steels with different chemical compositions there is an optimal ratio of γ and α phases at which the wear resistance is highest.
