在不断增长的数据库和大规模生产设施的支持下，通过 P/M 方法生产的不连续增强铝 (DRA) SiC 晶须或颗粒增强铝合金基复合材料已向商业应用迈进。目前人们关注的是代表性 DRA 配方的弹性模量、塑性、延展性和韧性特性，以及以片材、挤压件和能够取代铍的光学和仪器级结构形式市售的 DRA。 36 参考文献
Discontinuously-reinforced aluminum (DRA) SiC whisker or particle-reinforced Al-alloy matrix composites produced by P/M methods have progressed toward commercial applications, supported by growing data bases and large-scale production facilities. Attention is presently given to the elastic modulus, plastic, ductile, and toughness characteristics of representative DRA formulations, as well as to the DRAs commercially available in the forms of sheets, extrusions, and optical and instrument grade structures able to supplant beryllium. 36 refs.
