What is Powder Metallurgy?- Definition, and Process
Powder metallurgy is a term covering a wide range of ways in which materials or components are made from metal powders. This process can avoid, or greatly reduce, the need to use metal removal processes, thereby drastically reducing yield losses in manufacture and often resulting in lower costs. Powder metallurgy is a metal forming …

On the one hand, powder hot forging maintains the characteristics of powder metallurgy process. The forging flow stress of powder preforms is much lower than that of ordinary fused cast materials because they contain about 80% porosity. Therefore, it can be formed at a lower forging energy, and at the same time, by reasonably designing the ...

Manufacturing Operations: Processing and Assembly Operations
Both metals (powder metallurgy) and ceramics can be formed by particulate processing. Deformation processes. In most cases, the starting material is a ductile metal that is shaped by applying stresses that exceed the metal's yield strength. To increase ductility, the metal is often heated prior to forming.

What is Swaging Process in Forging? Why Swaging Process? Applications
Swaging is a cold forming process in which metal is pressed or drawn into another shape through the use of a die. It turns an irregularly shaped piece of metal into a round or oval shape. The swaging process uses the full force of the tool to press the metal into shape. The die used should be harder than the material being forged.
