Powder metallurgy (PM) compared with other known and conventional manufacturing technologies, machining process should not or less necessary requirement, as standard parts with complex geometry in a wide composition range can be manufactured serially, parts having mechanical properties desired material can be produced easily, such as being minimal losses as for these reasons finds widely used in industry. In addition, this production method has many advantages such as low investment costs, the equipment used in flexibility, high productivity, easy to produce materials with different properties. A large majority of product produced by powder metallurgy is used in the automotive industry. Powder metallurgy production method is developing in time in our country as well as all over the world. Sintering is one of the most complex issues of powder metallurgy. Sintering is heating process which causes substantially increased strength and improvement mechanical properties of particles will bond together. Sintering enables the connection to particles of contacting each other at high temperature. This connection may consist of solid atomic movements below the melting temperature but in many cases, it is accompanied by generation liquid phase. Sintering occurs with diffusion of atoms at high temperature and reduction of small particles surface energy. The purpose of this work that we have done, in aluminium alloys that is widely used in daily life and therefore in industry, it is to show the effects of the sintering process.
