摘要
Co对易磨削(1％V)的超硬型W-Wo和Mo系高速钢性能影响的研究表明,随Co含量的提高,二次硬度上升,3％-5％Co还可提高钢的强韧性,8％Co则有明显的脆化作用。新的低Co超硬高速钢Co3N在硬度、红硬性、强度、韧性和可磨削性诸方面皆达到M42的水平。
The investigation about influence of cobalt on properties of superhard W-Mo and Mo system high speed steel (HSS) containing 1 % V had observed that the secondary hardness rised with the increasing of cobalt, and the strength and toughness could be increased in the range of 3%- 5% Co. When cobalt content arrived to 8%, the brittleness would be appeared. A new type of superhard high speed steel, Co3N, with low cobalt content and the same hardness,red-hardness, strength, toughness and erindability of M42, was developed.
