The deformation and surfaceflow pattern of particles as well as the mechanism of consolidation have been cla-rified experimentally. The distribution of high temperature area is in agreementwith the result of numerical simulation by Williamson. A model for the explosiveconsolidation was given. Key words： explosive consolidation    shock wave    metallic powder 收稿日期: 1990-05-18      基金资助:国家基金委员会资助项目;;863高技术项目 服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 高举贤 邵丙璜 张科 郑哲敏 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1990/V26/I5/125 1 Perry R W, Kantrowitz A.
