martensite

• Solution solide sursaturée de carbone dans le fer alpha, dure et fragile, formée lors d'une trempe rapide de l'acier pour supprimer la formation de perlite et responsable de la dureté de l'acier trempé.

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.

   Martensite

   • 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.
