摘　　要：分别从原材料、烧结工艺及其后处理、强韧化和杂质影响等方面较系统地介绍了国内外近十年来在高比重钨合金领域所取得的进展,并从这些方面详细讨论了影响高比重钨合金性能的具体因素。在此基础上对钨合金今后的发展方向提出了意见。In this paper,research and development advances in tungsten heavy alloys at home and abroad in recent years are reviewed systematically,in terms of raw materials,sintering process and its subsequent treatment, strengthening-toughening treatment, and the influence of impurities etc. The factors which influence properties of tungsten heavy alloys are discussed detailedly. And future development directions in this area are suggested.
