What is powder metallurgy technique?

This process is known as powder metallurgy technique. The Properties Characterization was measured by doing density and porosity test, Thermal Gravimetric Analysis (TGA), and Scanning Electron Microscopy (SEM). Keywords: porous metals, pressing method, physical properties.

Are there any books on powder metallurgy?

There are books on scientific aspects of powder metallurgy, but details of technological aspects are not available. The emphasis has been not to treat the present book as a handbook, but as a handy textbook. The existing books either deal with the subject too elaborately or leave out some of the recent but important technological developments.

What is the flowability of metal powders for additive manufacturing?

The flowability of metal powders for additive manufacturing can be measured by a variety of methods, with funnels being the simplest ones, thus widely accepted in the AM industry and supported by international standards (ISO and ASTM). What is lacking is a good understanding of what is an acceptable flowability value for a given alloy.

What is the difference between powder metallurgy and hot forging?

The combination of powder metallurgy and forging is able to produce extremely high quality parts. A part is powder manufactured with about 15%-20% porosity, and then hot forged. Typically the forging is flashless. Hot forging eliminates porosity, increasing the density of the part.
