Özet
Increasing density is the best way to increase the performance of powder metallurgy
materials. A conventional powder metallurgy processing can produce copper green compacts with
density less than 8.3g/cm3 (a relative density of 93%). Warm compaction is a simple and
economical forming process to prepare high density powder metallurgy parts or materials. Cu-Sn
matrix composites with %2 weight fractions of reinforcement particles were prepared using warm
compaction and sintering. Micro-structural aspects were observed by an optical microscope.
Density, hardness and wear tests were also performed. Abrasion resistance measurements were used
to study the abrasive behaviors of Cu-Sn matrix and its composites. The effects of reinforcement
and preparation methods on the microstructure and mechanical properties of composites have been
investigated.
Keywords: Cu-based composite, warm compaction, sintering, Al2O3, SiC, B4C.
