Experimental investigation of the combined press powders elektrogidroimpulsnogo

Metallurgy and materials technology. Mechanical engineering

The results of experimental researches of combined processes electrohydraulicpulse compression and pre-extrusion billets in rigid compression moulds by vibration formation and hydrostatic pressing are presented. The efficience of the use of combined processes for high-density products of ceramic and metal powders is established. The average density of the products and the durability increased by 20-25 %. New perspective schemes of the combined pressing are developed.
