| الوصف: | International audience; Ferrium® M54® exhibits an excellent UTS/K1C balance allowing its application in aeronautical structures. Thissteel belongs to the Co-Ni UHS steels family with M2C nanometer-size carbide precipitation during tempering.These steels provide very high strength with a very good fracture toughness thanks to the M2C fine precipitationduring tempering, but also because coarse particles are dissolved during austenitizing without grain coarsening.The goal of this article is to identify the different carbide populations in M54®. A small addition of Ti in M54®forms a Ti-rich MC carbide precipitation that is stable at high temperature. Consequently, during austenitizationat 1060 °C, all other types of coarse carbides are dissolved in the matrix without grain coarsening. As a very smallpart of the initial carbon content is needed to form MC carbides, efficient and intensive nanometric M2C carbideprecipitation takes place during tempering, leading to very high final strength. Due to this double precipitationof carbides in M54®, the steel achieves an outstanding UTS/K1C balance. |
