The uniaxial compressive deformation experiments on ZCuSn10 copper alloy billet with different original semi-solid organizations prepared by strain induced melt activation (SIMA) process were carried out using Gleeble-1500 thermo-mechanical simulator. The effect of pre-deformation and compressive deformation conditions on true strain–stress curves and organizations of semi-solid billet were analyzed. And the liquid flowing law was studied by analyzing the macroscopic morphology and microstructure of ZCuSn10 copper alloy after the compression. The results show that deformation resistance reduces with increasing the pre-deformation amount and deformation temperature. The deformation temperature of uniaxial compression has a greater impact on the peak stress of semi-solid ZCuSn10 copper alloy during uniaxial compression, but has a less impact on steady stress. As same as the compressive deformation of solid metal, there are three typical compression areas in semi-solid ZCuSn10 copper alloy during uniaxial compression, namely difficult deformation zone (zoneⅠ), large deformation zone (zoneⅡ)and free deformation zone (zoneⅢ). The contents of liquid phase in zonesⅠ,Ⅱ andⅢ are 15.23%, 5.31% and 20.12%, respectively. And the liquid phase flowing occurs among different deformation zones, a small amount of liquid phase in the difficult deformation zone flows to the large degree deformation zone, and a large amount of liquid phase in the large degree deformation zone flows to the free deformation zone.
