Martensite — Wikipédia

For steel with 0–0.6% carbon, the martensite has the appearance of lath and is called lath martensite. For steel with greater than 1% carbon, it will form a plate-like structure called plate martensite. Between those two percentages, the physical appearance of the grains is a mix of the two. See more Martensite is a very hard form of steel crystalline structure. It is named after German metallurgist Adolf Martens. By analogy the term can also refer to any crystal structure that is formed by diffusionless transformation See more Martensite is formed in carbon steels by the rapid cooling (quenching) of the austenite form of iron at such a high rate that carbon atoms do not have time to diffuse out of the crystal structure in large enough quantities to form cementite (Fe3C). Austenite is gamma … See more • Comprehensive resources on martensite from the University of Cambridge • YouTube Lecture by Prof. HDKH Bhadeshia , from the University of Cambridge See more • Eutectic • Eutectoid • Ferrite (iron) • Maraging steel • Spring steel • Tool steel See more WebMar 6, 2024 · Lath martensite is a common martensite structure that forms in low to medium carbon steel, maraging steel, stainless steel, and other iron-based alloys.
