XD技术是一种经济而通用的制造各种韧性复合材料、包括高温金属间化合物的方法。目前改进铝合金力学性能的途径除发展铝锂合金外,另一种方法就是使用长石墨纤维或陶瓷纤维作为增强剂。该法存在的问题是成本高,制造复杂形状比较困难,而且获得可靠结构的 XD technology is an economical and versatile method of making various ductile composites, including high temperature intermetallics. Current ways to improve the mechanical properties of aluminum alloys In addition to the development of aluminum lithium alloys, another method is to use long graphite or ceramic fibers as reinforcing agents. The problem with the law is the high cost, the difficulty of creating complex shapes, and the reliable structure
