摘 要: 半固態(tài)材料具有觸變性和優(yōu)良的組織結(jié)構(gòu)，即成形零件質(zhì)量好， 力學(xué)性能與鍛件的力學(xué)性能相近， 成形零件的尺寸和精度能達(dá)到凈近成形或凈終成形， 而傳統(tǒng)陶瓷的制備主要根據(jù)粉末冶金方法通過(guò)成型和燒結(jié)工序完成。綜合半固態(tài)金屬加工技術(shù)、 粉末冶金以及21世紀(jì)陶瓷成形發(fā)展的方向，提出了一種新型成形方法—偽半固態(tài)觸變成形， 從而為陶瓷復(fù)合材料以及高熔點(diǎn)材料在更多領(lǐng)域的應(yīng)用起到了推進(jìn)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
