1. Metallographic structure of martensitic wear-resistant ductile iron Martensite Martensite is the main matrix structure, generally high-carbon hidden needle martensite. Under the metallographic microscope, it is in the form of needles or laths, with fine and interlaced layers. Due to the supersaturated solid solution of carbon in α-Fe, it has high hardness and high strength, […]
