Promising trends in the development of methods of fabricating structural powder materials (survey)

In the new, millennium a trend focused on making improvements in existing technologies of powder metallurgy and on the development of new and promising trends in the creation of powder structural materials is observed. The development of the technology of powder metallurgy, is intended to improve methods of warm and injection molding, laser and mechanical alloying, and nitration of high- and low-alloy steels. Considerable attention has been paid to the production of structural materials made of intermetallic compounds, materials, the properties of which exhibit functional gradients. There has also been emphasis on creating nanomaterials fabricated by the sol-gel method, mechanical alloying, and powder spraying.
