摘    要:MP35N合金是一种高性能医用钴基合金,具有优良力学性能、耐腐蚀和良好的生物相容性等优点,在医疗器械和航天航空具有广阔的应用前景。综述MP35N合金的力学性能和两种强化工艺冷变形和时效处理对其性能的影响,将MP35N合金强化机理分为4类并加以详细阐述,描述不同强化机理的发展历程和现状。分析MP35N合金不同强化机理的优缺点和未来关于MP35N合金的研究思路。

Abstract: MP35N alloy is a kind of high performance medical cobalt based alloy,which has good mechanical properties, corrosion resistance and good biocompatibility. It has wide application prospect in medical devices and aerospace. The mechanical properties of MP35N alloy and two kinds of strengthening processes on properties of the alloy were summarized. The strengthening mechanism of MP35N alloy was divided into four categories, and the development and current situation of different strengthening mechanisms were described. The advantages and disadvantages of different strengthening mechanisms of MP35N alloy as well as the ideas about MP35N alloy in the future research were analyzed.
