  • frAcier dont la teneur en carbone est d'environ 0,8 %, qui, lors d'un refroidissement lent depuis la phase austénitique, se transforme entièrement en perlite, une structure lamellaire de ferrite et de cémentite.

A type of steel that has a specific carbon composition (approximately 0.8% carbon) which, when cooled slowly from the austenite phase, transforms entirely into pearlite, a lamellar structure of ferrite and cementite.

  1. Eutectoid SteelC2formal

    A type of steel that contains exactly 0.8% carbon, which upon cooling transforms from austenite into a lamellar mixture of ferrite and cementite known as pearlite.

    • Eutectoid steel is often used in the production of high-strength rails.
    • The microstructure of eutectoid steel consists of alternating layers of ferrite and cementite.
    • Heat treatment of eutectoid steel can produce a very hard and wear-resistant material.
