The influence of
retained austenite in high chromium cast iron on impact fatigue wear was
investigated by using MLD-10 Wear tester with an attached apparatus. It
is indicated that retained austenite in microstructure can inhibit the
initiation and propagation of fatigue crack, improve the resistance to
impact fatigue and decrease impact fatigue wear.
