The microstructure and properties of CuFe10 alloys irradiated by high current pulsed electron beam (HCPEB) with different pulse number were studied. The crater and Fe-rich spheres with diameter from 100 nm to 1 m existed on the remelting surface, which indicated that liquid phase separation occurred during HCPEB treatment. Compared with the initial sample, the microhardness and corrosion resistance of CuFe10 alloy after 30 pulses of HCPEB treatment were remarkably improved.It could be attributed to the liquid phase separation and grain refinement occurred on the surface of CuFe10 alloy in the process of rapid remelting and solidification induced by HCPEB.
