He discusses the powder metallurgy technologies of the 1980s from ten aspects. There is a wealth of research end: in the United States, there is no shortage of any kind of metal powder, especially iron powder, the production capacity has reached a new level, with an annual output of almost up to 330,000 tons in 1981, slightly expanded By 1985, the annual output of up to 457,000 tons. The current consumption of iron powder even though
