The structure, hardness, and impact strength of high chromium
cast irons was investigated. From the Fe- Cr- C phase diagram,
a composition with 74.8 wt% Fe, 21.5 wt% Cr, and 3.7 wt% was
selected along the austenite-M₇C₃ eutectic trough. This composition
was bracketed by others with slightly different amounts of...
