摘要

摘要: Ni3A1型金属间化合物虽有一些固有的优点，如高温强度好，比重小，抗氧化和抗腐蚀性能好，等等，但在发展Ni3A1基高温合金过程中遇到了塑性差，中低温强度较低和高温下强度下降快等问题，为这类合金的发展和应用造成了障碍。本文在文献综述分析和探索试验的墓础上介绍了解决多品Ni3A1基合金塑性低的途径提出了在Ni3A1垫固济体中动加一牛金属型化合键和利用反沉淀质点强化等改善这类合金强度的方法.对于Ni3A1基合金的成份选择和LI2型点阵结钩的稳定性的判据也作了扼要阐述，并介绍了一些Ni3A1基合金的应用实例。

Abstract: Since intermelallic compound Ni3Al has some advantages, such as，high trength at elevated temperature, low density，high resistances to oxidation and corrosion，it is necessary to develop Ni，AL base superalloys for high temperature structures.However, the low ductility of polycrystal Ni3A1，relatively low strength in the temperature range below 700℃ and the sharp decrease of strength with temperature in the elevated temperature region make the development and application difficult, These problems have been solving recently, The ways to solve these problems have been discussed in this review combined with expcrimental work in this insti tute.The low ductility of polycrystal Ni3Al have beensolving by the development of Ni-rich Ni3Al base alloy systems and the addition of boron in these kind alloys.The improvement of strength has been achieving by the way of alloying to increase the part of non-metal chemical bond between atoms and the reverse precipitating of second phase particles when temperature raises,The criteria for the stability of LI2 tYPe structure and the composition design of Ni3Al base alloys have been discussed, and the chemical composition and mechanical properties of several developed casting polycrystal and DS Ni3Al superalloys have been also summerized in this literature review.
