Powder Metallurgy is a technology which involves spending considerable time and effort in converting the starting material to the required powder form and then even further time and effort in "sticking" the material back together again to produce a more or less solid object.
Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal processes 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 also used to make unique materials impossible to get from melting or ...

Answer: a Explanation: Porosity is simply the empty space in the product material. The production of highly porous parts by powder metallurgy using suitable spacer materials is a wellestablished technique for titanium and stainless steel.
Powder metallurgy, fabrication of metal objects from a powder rather than casting from molten metal or forging at softening temperatures. In some cases the powder method is more economical, as in fashioning small metal parts such as gears for small machines, in which casting would involve considerable machining and scrap loss.
