在所有半固态镁合金试验中，水淬试样的晶粒密度都大于重力铸造的金属型试样的晶粒密度。这表明在半固态成型过程中，晶粒有很强的长大合并的趋势。
The density of the quenchinching samples was higher than that of the metal-mould ones and the grains were much easier to grow and merge in the shaping of the semi-solid alloys.
研究了半固态等温温度、搅拌速率和挤压力对成型件质量的影响。
The influence of the isothermal temperature, the stirring speed and the extrusion pressure on quality of the formed parts were investigated.
