外氧化法制备Al2 O3/Cu复合材料的组织与性能
Microstructure and Property of Al2 O3/Cu Composite Prepared by External Oxidation
摘要
Abstract
The Al2 O3 particles dispersion strengthened copper matrix composites were prepared with the condition of not adding any Cu2 O as oxidant,but by external oxidation in a furnace to generate Cu2 O oxidant in advance, internal oxidation to generate Al2 O3 and sintered in a vacuum furnace,and then cold drawing after hot extrusion. The microstructure of experiment materials were analyzed by SEM,and the hardness and conductivity were tested. The results showed that with the increase of Al203 ,the hardness of Al2 O3/Cu composites would increase,while the conductivity would decrease. After hot extrusion deformation,the Rockwell hardness of Al2 O3/Cu composites would increase with the increase of deformation ratio, but the conductivity would decrease. The hardness and electrical conductivity of 1. 04wt.%Al2 O3/Cu composite with 24. 8% hot extrusion deformation ratio can reach 69. 2 HRB and 73. 6% IACS.关键词
