Özet:

Powder metallurgy is method which is able to process work piece by following the phase of metal and ceramic powder production, powder forming, and sintering. The powder metallurgy is used in many ares especiailly in autımotive industry. Powders metalurgy provides advantages if comparing with conventiounus methods such as: low loss of raw material and low unit of production cost (in processing of scores process work). Powder metallurgy is able to process of process works which has complex geometry or high melting temperature. Also material can process with powder metallurgy method which can not alloy with conventional techniques. Powder forming constitutes an important area in powder metallurgy. In this paper, conventional powder forming methods such as: single action pressing, double action pressing, hot isostatic pressing, cold isostatic pressing, powder forging, powder injection moulding, powder extrusion, powder rolling, slip casting, tape casting methods are expressed and compared.
