چکیده:

Guidelines Aluminium and its alloys due to the ease of formability and lightweight have a wide application in variety of industries including aerospace, automotive, electronics and so on. But because do not have enough strength in some engineering applications, many research has been on the production of aluminium composites by mechanical alloying process in recent years. In this study the effect of annealing temperature on the synthesis of aluminium carbide product whit mechanical alloying process has been studied. Phase formation and particle size identified by scanning electron microscopy and X-ray diffraction analysis and determine the optimal grinding. The experimental results show that no chemical interaction occurred between Al powders and carbon black during mechanical alloying processing and mechanical alloying causing high deformation of powders, which results in the formation of amorphous structure. after the mechanical alloying for 30 hours, and the annealing temperature in 550 ºC resulted in higher deformation of Al particles and caused a high internal energy, This energy facilitated the formation of the Al4C3 phase during sintering
