Powder Metallurgy Open Access Journals

Powder metallurgy may be a term covering a good range of the way during which materials or components are made up of metal powders. PM processes can avoid, or greatly reduce, the necessity to use metal removal processes, thereby drastically reducing yield losses in manufacture and sometimes leading to lower costs. metallurgy may be a technology which involves spending considerable time and energy in converting the starting material to the specified powder form then even further time and energy in “sticking” the fabric back together again to supply a more or less solid object. There are, in fact, many good reasons why metallurgy could be chosen because the preferred route for the manufacture of a product. In broad terms, these reasons separate into two categories: the assembly quantities at which metallurgy would be the method of choice is in fact hooked in to how difficult it might be to make the form by a special route, but, generally, would be a minimum of within the order of tens of thousands of parts per annum. Virtually all iron powders for PM structural part production are manufactured using either the sponge iron process or water atomisation. Nonferrous metal powders used for other PM applications are often produced via variety of methods.
