中文摘要：
提出一种制备半固态浆料的新方法—摆动振荡法。采用该方法制备了A356铝合金的浆料。结果表明：摆动振荡可有效地防止稳定凝固壳的形成,可制备出组织优良的半固态浆料,其初生α（Al）的等效直径在60μm以下,形状因子可达0.8以上,特别地,可以大幅度提高浇注温度。
英文摘要：
A new method of angular oscillation（AO） to produce sound semi-solid slurry for rheoforming was proposed.The semi-solid slurry preparation of A356 aluminum alloy was carried out,applying this method of AO.The results show that the limited angular oscillation can prevent the formation of solid skin effectively;the sound semi-solid slurry can be obtained by properly controlling inclined angle of barrel and oscillation intensity.The primary α（Al） particles have an average diameter smaller than 60 μm and an average shape factor larger than 0.8.Especially,the superheat temperature of melt can be increased to a higher temperature.
