Ultrasonic molding of products from finely dispersed powders

The article deals with the current state of the physics and technology of the process of ultrasonic molding (USM) of products from finely dispersed metal and non-metal powders. The relevance of a comprehensive consideration of the process is substantiated, structural and technological schemes for its implementation are presented, types of ultrasound sources – ultrasonic transducers and ultrasonic generators, as well as designs and methods for calculating concentrators (transformers) of ultrasonic vibrations are given. The results of experimental studies of the USM process as applied to fine powders of various physical and chemical nature are analyzed. Physical models of the USM process are presented and discussed.
