THE EFFECT OF ALLOYING ELEMENTS ON THE MECHANICAL PROPERTIES OF PM Fe-Cu BASED ANTIFRICTION ALLOYS

摘要

In this study the effect of different alloying contents including tin and lead on the mechanical properties of the sintered iron - copper based alloys was investigated. Hardness, tensile, compression and impact tests were used to determine the mechanical properties of the alloys. Hardness, tensile strength and compression strength decrease with increasing the lead contents. The impact strength has a different variation with lead and tin contents. Also, hardness, tensile strength and compression strength decrease with decreasing of the tin contents.
