Martensite. Martensite is formed in steels when the cooling rate from austenite is sufficiently fast. It is a very hard constituent, due to the carbon which is trapped in solid solution. Unlike decomposition to ferrite and pearlite, the transformation to martensite does not involve atom diffusion, but rather occurs by a sudden diffusionless The austenite-martensite interface might not be atomically flat, where a transition lattice zone could exist to continuously change the lattice structure 22,25,26. マルテンサイト系ステンレス鋼とは、13％のクロムを含むsus403・sus410を代表とした、常温でマルテンサイトの組織を持つステンレス鋼です。 マルテンサイト系ステンレス鋼は、フェライト系とオーステナイト系には劣りますが、耐食性を持ちます。 Tweezers made of 410 martensitic stainless steel. Martensitic stainless steel is a type of stainless steel alloy that has a martensite crystal structure. It can be hardened and tempered through aging and heat treatment. The other main types of stainless steel are austenitic, ferritic, duplex, and precipitation hardened. The martensitic transformation begins when the austenite reaches the martensite start temperature (M s) and continues until the lower transformation temperature (M t) is reached. In general, the higher the percentage of conversion to martensite, the stronger the resulting martensitic steel. These steels undergo post-quench martensitic tempering Martensite is the hardest structure of steel because of the way it is formed. Martensite is formed by diffusionless shear process, which means a solid-state transformation without diffusion.
