    摘要:

    概述了半固態(tài)金屬加工制漿工藝的發(fā)展以及研究現(xiàn)狀，介紹了具有代表性的幾種半固態(tài)加工技術(shù)及其相應(yīng)的制漿技術(shù)，總結(jié)了強(qiáng)制對流條件下非枝晶組織的形成機(jī)制。流程簡潔、成本低廉的流變成形工藝路線成為當(dāng)前的發(fā)展方向，形成具有高密度晶核的半固態(tài)漿料是獲取高質(zhì)量半固態(tài)加工部件的必要條件。

    Abstract:

    Research and development of semisolid metal slurry processing technology was outlined; and a few representative SSM (semisolid metal processing) methods and the corresponding slurry processing technologies were presented; moreover, the formation mechanism of non-dendritic microstructure under coerced convection condition was summarized. The rheoforming route, whose process flow was simple and prime cost was low, has become the development direction at present. The necessary condition of manufacturing high-quality semisolid processed parts is that the supplied semisolid slurry has high density of nuclei suspending uniformly in the bulk melt.
