The composite powders were characterized by using XRD, SEM, TEM. It has been shown that tungsten and copper are homogenously mixed within each particle and the average particle size is about 240 nm, in which the tungsten particles have an average grain size of 16 nm. Key words： tungsten--copper    nano--powders    spray drying 收稿日期: 2003-03-17      ZTFLH:  TG383   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 杨明川 宋贞桢 卢柯 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y2004/V40/I6/639 [1] Cai Y X, Liu B W.
