Özet:

 

In this study, firstly, AA7075 metal powder which average particle size 43.9 µm were manufactured by using gas atomization method. Thereafter with mechanical alloying method which powder metallurgy manufacturing methods, 10% B4C particle reinforcements that average particle size of 49.5 µm by participating into AA7075 metal matrix composite powder mixtures were prepared. They were milled for different durations (0-8 hrs) in a high energy planetary ball mill. From these milled powders; 550°C and under pressure 500 MPa, composite materials were produced by the method of hot pressing. In SEM analysis, after 4 hrs with mechanical alloying method, B4C particles which were homogenously distrubuted  into the matrix of AA7075 were seen. Powders size increased to 1 hr and then decrease. In order to determine produced composite material's microstructural properties SEM analysis and determine physical and mechanical properties, density test and hardness test was applied. As a result of the experiments, composite density increased to 1 hr and then decrease. The hardness of composite was increased with increasing milling time and the rate of reinforcement.
