摘要 粉末冶金高速压制可以以低成本大批量制备高性能的粉末冶金零部件,零件的密度、性能等接近粉末锻造,而成本却远低于粉末锻造。近年来,粉末高速压制技术还与模壁润滑、温压或者复压复烧等技术相结合,使其应用领域进一步拓宽。综述了粉末冶金高速压制的原理及应用、粉末高速压制的数值模拟及致密化机制研究进展,指出了未来重点研究的方向。 Powder metallurgy parts with high performance can be prepared by powder metallurgy high velocity compaction economically. The density and properties of the parts are close to the powder forging,but the cost is much lower than that of powder forging. In recent years,the powder metallurgy high velocity compaction technology is combined with the technology of die wall lubrication,warm compaction or re-pressing and re-sintering,so that its application field is further broaden. The principle and application,numerical simulation and the research progress of densification mechanism of powder metallurgy high velocity compaction were summarized,and the future research directions were also pointed out.
