NiAl及金属间化合物结构材料改善室温塑韧性及制备工艺的研究进展

Advances in Fabrication Process and Improvement of the Ductility and Toughness of NiAl and Intermetallic Compounds for Structural Application

摘要:

本文以NiAl基合金为主,兼顾FeCo,MoSi2等不同晶体结构的金属间化合物结构材料,重点论述了近年来围绕提高其室温塑韧性研究工作的进展;由于这类材料的本征脆性,导致了加工成形性很差,而且制备工艺本身也是改善性能的一条重要途径,因此对NiAl基合金等金属间化合物结构材料在制备方面的研究进展也加以综述.

Abstract:

The progresses in the ductility and toughness improvements for the structural materials of intermetallic compounds, especially the NiAl-based alloys, are reviewed in this paper. Owing to their intrinsic brittleness, the forming capability of these materials is poor. On the other hand, the advances in the fabrication process are also included in this paper since the materials properties are closely related to it.
