Experimental Investigation of Nb/Cu Composite Fabricated by Liquid Penetration

摘要:

研究了金属Ｎｂ液态渗Ｃｕ制备复合材料的方法，并通过对Ｎｂ／２０Ｃｕ复合材料的组织分析和性能研究，确认Ｎｂ／２０Ｃｕ复合材料比纯铌粉末冶金材料的力学，电学，热学和抗氧化性能均具有所提高，从而为改善钝铌制品的使用性能提供了试验依据。ｒｍｈｊ ｔｌｆ

Abstract:

A liquid penetration method for Nb/20Cu composite fabrication is presented. The microstructure and the properties of the Nb/20Cu composite are also investigated in detail. The results show that the electrical and thermal conductivities, oxidizationresistance and mechanic properties of Nb/20Cu are better than those of pure Nb made by powder metallurgy. It provides an experimental base for improving property of Nb products.
