The Influence of Fe on the Strength and Ductility of Cu-10Sn-2Zn Based Alloys

Abstract:

The In situ iron nanoparticle reinforced Cu10Sn2Zn alloy was fabricated by centrifugal casting in vacuum chamber with a medium frequency electrical furnace. The major challenge in development of this alloy is to fide an approach to strengthen copper alloys with the increase of ductility. In this paper, we fide an effective way to balance the strength and ductility by identifying three essential structural characteristics for nanoparticles: in-situ formation in molten metal, smallest feature size finer than 10 nanometers and coherency with surrounding matrix. The tensile strengths and the elongation of ZCuSn10Zn2+Fe1.5% were 550Mpa and 42%respectively, which were remarkably improved compared to ZCuSn10Zn2.
