| Abstract | ||
| commercially pure copper matrix composite reinforced with ( 0,2,4,6,8,10 and 12vol % ) of ( SiC ) prepared by powder metallurgy technique. , then The mixture was mixed mechanically by using rotating mixer for two hour and frequently mixer for five minute for each sample . The mixture was cold pressed uniaxially at (350 MPa) using die of (12)mm diameter and height (100)mm and sintered at (900 oC) for two hours and studying the effect of reinforcement content on mechanical and metallurgical properties were studied . The results showed decrease in values of Green & Bulk Density and increasing the percentage of true porosity and increase in values of Vickers hardness and yield compressive resistance and decrease in wear rate with increase reinforcement content with improvement of properties after centering . | ||
