Abstract

The powder metallurgical process is relatively new and has several advantages over the casting process. However, this process cannot completely replace the function of the casting process. Each process has advantages and disadvantages. In this study determine the effects and variations of the sintering pressure and temperature on the value of porosity, microstructure, and hardness. with the powder metallurgy method, with the basic ingredients of pure aluminum powder with the addition of iron sand powder. The pressure variations that we use are 4000, 4500, and 5000 Psi. With sintering temperatures of 400°, 450°, and 500°C. For data collection, we use density testing, microstructure testing, and hardness testing. From the results of this test is obtained. The greatest hardness value is at a pressure of 4000 Psi at a sintering temperature of 450°C at 64.83 HRB, and the lowest hardness value is found at a pressure of 6000 Psi at a sintering temperature of 450°C at 23 HRB. This shows that the sintering pressure and temperature greatly affect the density, microstructure and hardness values.
