Abstract

AbstractThis study investigates the impact of cooling rate after destabilization at 980 °C on the microstructure of 23 wt pct Cr–2.7wt pct C hypoeutectic high-Cr cast iron. Lowering cooling rate intensifies the secondary carbides formation, depleting carbon in austenite. This raises the martensite start temperature and lowers the bulk hardness. We thereby provide evidence explaining the origin of the sensitivity to cooling rate in high-Cr cast irons.
