人们对粉末冶金发展趋势的关心通常集中在改进制粉技术、发展适应更多用途需要的材料和找出更好的成形零件的方法等三个方面。这三个方面相互联系。新的制粉技术能够改善现有材料的性能,在很多情况下还导致新材料的开发。虽然材料的研究取得了成果,发展制造业中实用新工艺的大量工作还有待于进行。 Concern over the trends in powder metallurgy has often focused on three areas: improving milling technology, developing materials that are better suited for more uses, and finding better ways to form parts. These three aspects are interrelated. New milling technology can improve the performance of existing materials and in many cases lead to the development of new materials. Although material research has yielded fruitful results, much remains to be done to develop practical new techniques in the manufacturing industry.
