介绍了近年在半固态铝合金的设计开发、合金半固态坯料的制备以及半固态触变成形的数值模拟和试验方面的研究状况,以及取得的主要研究成果。提出了半固态合金设计的新思路与新方法,并在国际上首次成功试制出直径500mm的半固态浆料锭坯,浆料组织均匀细小,无缺陷,完全符合半固态成形要求,达到国际领先水平。
This paper presents the progress in the investigation of semisolid aluminium alloy design, billet preparing for semisolid processing, the numerical simulation and experimental studies on thixoforming as well as some main achievements in this field. We have presented a new method of semisolid alloy design, and successfully produced for the first time in the world the large scale billet of 500mm in diameter for semisolid slurry. The grain size is fine and uniformly distributed in the billet, which satisfies t...
