Consolidation of Powder Materials During the Production of Products by Hot Isostatic Pressing

The development of powder metallurgy is largely determined by the improvement of the quality of materials. The problems of creating new materials with the specified properties can be successfully solved by the methods of powder metallurgy. Metal powders have unique properties: high hardness, refractoriness, a given porosity. The technique of isostatic pressing for obtaining parts from metal powders has become widely used abroad. The use of isostatic pressing allows you to create blanks with a denser and more uniform structure than when compacting in another way. To obtain a product of specified shapes and sizes with the appropriate structure and properties, the consolidation of powders is used. This can be done using various technological processes: pressing, sintering, rolling, extrusion. This article discusses the main methods of consolidating powder materials in the production of products by hot isostatic pressing.
