摘　　要：利用XRD、SEM、TEM等检测手段,对制备新型W-Al合金过程中的产物显微组织进行研究和标定。结果表明:水热产物转变为混合氧化物粉体;且Al的存在对WO3的还原起催化作用。Using XRD, SEM, TEM and other detection methods, the microstmcture of the products during the preparation of new W-A1 alloy was studied and calibrated. The results show that the hydrothermal products change into mixed oxide powders, and the presence of AI plays a catalytic role in the reduction of W03.
