Research on Powder Metallurgy Short Process Forming and Consolidation Technique and Its Prospects

Based on the resuhs gained from the integrating researches on powder materials-processing techniques-equipments carried out in South China University of Technology in the past two decades, the novel powder metallurgy short process forming and consolidation techniques, with elaboration stressed on the research progress and application status of warm compaction forming, high-velocity compaction forming, spray forming, integrated multi-field powder metallurgy form- ing and consolidation techniques, are mainly introduced. Expanding the content of existing powder metallurgy technical specifications with insight may inject new vigor into the traditional powder metallurgy forming and consolidation. The continuous emergence of novel techniques will not only accelerate the rapid development of the advanced manufacturing and high-tech industries, but will also bring a bright future for materials engineering and manufacturing industries.
