为了使材料获得任一单独组成相常无法达到的综合特性,现在人们对一系列铝合金基复合材料制备技术的兴趣已越来越大。这些复合材料依其第二相的几何形态可大致分为两类。在以纤维和晶须增强的复合材料中,第二相的纵横比范围为100～10000,而许多以碳、硼、SiC和Al_2O_3~-纤维增强的复合材料做为特殊的高强度和高弹性模量结构件应用现已在进行大量工业生产。第二类复合材料则含有弥散的固体润滑物或坚硬陶瓷粒子,它们被广泛应用于各种摩擦领域。当纤维、晶须或颗粒进
In order to make the material available to any combination of individual composition is often not achieved with the comprehensive characteristics of the people of a series of aluminum alloy composite material preparation technology has become increasingly interested. These composite materials can be broadly divided into two categories according to their second phase geometry. In the composite reinforced with fibers and whiskers, the second phase has an aspect ratio in the range of 100 to 10000, and many composites reinforced with carbon, boron, SiC and Al 2 O 3 - fibers are particularly high strength and high elasticity Modular structure applications are now undergoing large-scale industrial production. The second type of composite material contains dispersed solid lubricants or hard ceramic particles, which are widely used in various fields of friction. When fiber, whisker or particles into
