英文摘要	Powder metallurgy decorative pattern steel is widely used in various tool materials because of its beautiful surface pattern and excellent mechanical properties. In this work, the powder metallurgy decorative pattern steel with herringbone pattern was used as a research object. The microstructure and fracture process of the powder metallurgy pattern steel decorative were investigated under two heat treatment states through SEM, EDS, XRD, hardness test, tensile test, bending test, and in-situ tensile test. The results show that the pattern is composed of black RWL34 with high C content and white PMC27 martensitic stainless steel with relatively low C content. The quenched matrix is martensite, the annealed matrix is ferrite, and the precipitation phases are all M23C6 carbides with Cr as the main component. The quenched powder metallurgy decorative pattern steel has excellent mechanical properties, which include high strength and good toughness. Under the action of tensile stress, the cracks is preferentially produced in the M23C6 carbides of the powder metallurgy decorative pattern steel under two heat treatment states, and then propagated along the carbide boundary in the RWL34 band, finally with more cracks connected, propagated and fractured. © 2022, Materials Review Magazine.
