日本金属系材料研究开发中心完成一份“关于金属半凝固加工程序调查研究报告”指出:金属材料的半凝固(半熔融)加工技术一旦开发成功,则:(1)一般制造程序无法生产的有显著比重差的各种金属与润湿性较差的各种金属,均可望制造合金;(2)粉末冶金中因成本过高无法生产的材料也可望生产;(3)积极利用淤浆状的固液“共存相”,在与太空相同的无重力条件下,也有生产材料的可能。此外,可直接控制合金材料的凝固组织,生产品质均匀的微细粒结晶合金。
Japan Metal Materials Research and Development Center to complete a << on the metal semi-solidification process research report >> that: metal materials semi-solidified (semi-molten) processing technology once developed, then: (1) the general manufacturing process can not produce Significantly poor the proportion of various metals and poor wettability of a variety of metals are expected to manufacture alloys; (2) powder metallurgy can not be produced due to high cost of the material is expected to be produced; (3) the active use of slurry The solid-liquid “coexistence phase” also has the potential to produce materials under the same gravity-free conditions of space. In addition, direct control of solidified alloy material organization, the production of uniform quality of fine grain crystalline alloy.
