This paper introduced chemical tint colour metallography for carbides of high speed steel W18Cr4V,to demonstrate quenching,tempering and annealing. The selenium acid agent made various carbides and alloy content sill different coloures.

• 该文采用彩色金相化学染色技术显示淬火态、回火态与退火态的W18Cr4V高速钢中的碳化物，硒酸试剂使不同类型及其不同合金含量的碳化物以不同的色彩呈现。
