ABSTRACT:The In-situ iron nanoparticle reinforced ZCu10Sn2ZnFe1.5Co1 alloy was fabricated by centrifugal casting in vacuum chamber with a medium frequency electrical furnace. The processes of solid solution of ZCu10Sn2ZnFe1.5Co1 alloy are investigated and the process optimization conditions are confirmed by microstructure observation and the tensile test measures. The results show that proper solid solution can improved the microstructure and the mechanical property. By 700℃×120min solid-solution treatment, brittle δ phase is almost entirely dissolved into the matrix, the tensile strength and the break elongation of ZCuSn10Zn2Fe1.5Co1 reach 485.8 MPa、51.84％ respectively after, increased by 15.74％and 230.62％ than the original alloy.

Keywords:ZCu10Sn2ZnFe1.5Co1 alloy, solid solution, process optimization.
