Abstract
The current development of modern powder metallurgy materials and technologies
was reviewed. The basic characteristics, applications and developmental trend of traditional and advanced
powder metallurgy materials were also introduced. Meanwhile, the research and development of new
powder metallurgy technologies, such as mechanical alloying, powder injection molding, warm
compaction, spray forming, microwave sintering, spark plasma sintering, self
propagation high
temperature synthesis, sinter hardening, were also described. The article is issued in two parts.
