摘　　要：将W-15%(质量分数)Cu粉机械合金化后,研究无压和低温加压烧结条件下钨铜复合材料显微组织、相对密度的变化。结果表明,低温加压烧结能显著提高钨铜复合材料的相对密度,促进其烧结成形。W-15wt% Cu powder was mechanically alloyed by ball milling. The structure and relative density of specimen made by no pressure and low-temperature pressure sintering separately were analyzed. The results show that low-temperature pressure sintering can improve the relative density of tungstencopper composites obviously and promote the process of sintering.
