Abstract:This article investigates the effect of N content on the microstructure, mechanical properties and wear resistance of hypereutectic high chromium cast iron (HHCCI). With the increase of N content, the primary carbides are obviously refined, the austenite content increases, and the dispersed granular Cr2N precipitates. After quenching at 1000 °C, secondary carbides are precipitated from the matrix, the matrix transforms into martensite + retained austenite. With the increase of N content, the corrosion resistan… Show more
