9412196 Wang The award is for the development of a process and machinery for net-shape production of parts made from semi-solid materials. The materials could be metal alloys or metal-matrix composites. Semi-solid processing enables use of lower die temperatures, higher viscosity, lower part porosity, lower thermal shrinkage, and better grain structure. A screw injection molding machine has been modified for die casting of semi-solid material. The feasibility of changing properties of the castings such as solid fraction, particle size, etc. by manipulating process control variables will be investigated. Net shape die casting experiments to produce simple three-dimensional parts will be conducted. If the research is successful, the process may have a great impact on the die-casting industry and could make the traditional die-casting process obsolete.

[9412196]该奖项是为了表彰在半固体材料零件净成形生产工艺和机械方面的发展。材料可以是金属合金或金属基复合材料。半固态加工可以使用较低的模具温度，较高的粘度，较低的零件孔隙率，较低的热收缩率和更好的晶粒结构。对螺杆注塑机进行了改进，用于半固态材料的压铸。将研究通过操纵工艺控制变量来改变铸件的固体分数、粒度等性能的可行性。将进行网形压铸试验，以生产简单的三维零件。如果研究成功，该工艺可能会对压铸行业产生巨大影响，并可能使传统的压铸工艺过时。
