martensite

• 钢在快速冷却（淬火）时形成的一种硬而脆的碳在α-铁中的固溶体，可抑制珠光体的形成，是淬火钢硬度的来源。

A hard, brittle solid solution of carbon in alpha-iron, formed when steel is rapidly cooled (quenched) to suppress the formation of pearlite, and responsible for the hardness of quenched steel.

   A hard, brittle microstructure in steel formed by rapid cooling (quenching) from the austenite phase, consisting of a supersaturated solid solution of carbon in body-centered tetragonal iron.

   • The formation of martensite gives quenched steel its extreme hardness.
   • Martensite is a key component in the production of high-strength tools and blades.
   • The rapid cooling rate prevents carbon diffusion, resulting in a martensitic structure.
