In this study, the mechanical properties of Cu-316L composites produced by powder metallurgy
method were investigated. The particle sizes are 63 microns for 99.9% pure copper and 45 microns for the
reinforcement material 316L, respectively. Reinforcement amounts of the composites produced by powder
metallurgy method were determined as 1, 3, 5 and 10 wt.%, respectively. Raw powders were milled in a
ball mill for mechanical alloying at 400 rpm and 5:1 ball-powder ratio with the addition of 2% Stearic acid
as a process control agent for a total of 2 hours. After mechanical alloying, the composite powders were
pre-pressed in the mold, and then sintered in a protective argon gas atmosphere at 500 degrees for 2 hours
in a hot press device. The hardness, porosity, and tensile strengths of Cu-316L composites with different
reinforcement ratios fabricated by powder metallurgy method were examined and fracture surface
examinations were made.
