摘 要: 半固态材料具有触变性和优良的组织结构，即成形零件质量好， 力学性能与锻件的力学性能相近， 成形零件的尺寸和精度能达到净近成形或净终成形， 而传统陶瓷的制备主要根据粉末冶金方法通过成型和烧结工序完成。综合半固态金属加工技术、 粉末冶金以及21世纪陶瓷成形发展的方向，提出了一种新型成形方法—伪半固态触变成形， 从而为陶瓷复合材料以及高熔点材料在更多领域的应用起到了推进作用。

Abstract: The materials in semi-solid state have thixotropy property and good histology, namely the quality of the formed parts is very well, mechanical property is near to that of the forging. At the same time, the size and the precision can get to the net-near-forming or net-end-forming. But the traditional ceramics were manufactured through forming and sintering based on the powder metallurgy. The semi-solid metal forming, the powder metallurgy and development direction of the ceramics forming in 21 century were synthesized, a new forming method—the thixoforming in pseudo-semi-solid state was proposed. It plays a very big role in accelerating the ceramics composites and using high melt point materials in more fields.
Key words: pseudo-semi-solid; thixofroming; high melt point materials
