Conclusions
-
1.
The principles of a discrete contact theory of pressing have been formulated.
-
2.
Extensive experimental data have been accumulated on standard pressing techniques (pressing in closed die sets, hydrostatic and hot pressing).
-
3.
Special equipment has been built to meet the requirements of powder metallurgy; experience with its use has demonstrated, however, that the designs of the existing presses require modification.
-
4.
Investigations of new shaping techniques (vibratory, impact, hydrodynamic, explosive) have laid foundations for their wide application in industry.
-
5.
Too little attention is being paid to such shaping techniques as pressing with simultaneous spark sintering, ultrasonic pressing, hot casting, shaping in a magnetic field, etc. Work conducted with the aim of studying and employing such techniques will promote further technical progress in our country.
