摘要
近年来开发的高 Co Ni超高强度合金钢 ,以其合理的合金设计、极高的力学性能和使用性能而获得广泛的关注。高 Co Ni合金钢是典型的马氏体时效钢 ,它利用时效处理析出的细小弥散M2 C合金碳化物达到二次强化的目的 ,从而获得强度与韧性的最佳配合。作者从材料开发、性能。
The development and research status of ultra high strength steel enriched CoNi in recent years were summarized. Ultra high strength steel is notable for its rational design, excellent combination of mechanical and practice performance. Enriched CoNi alloy is typical aging martensitic steel, the superior performance is achieved by precipitating fine carbides during tempering. This type alloy was reviewed in many aspects, such as the material development, performance, microstructure and theoretial studies etc.
