Microstructural evolution and mechanical properties of hypereutectic Al-Si alloy processed by liquid die forging

The microstructural evolution and mechanical properties of a hypereutectic Al-Si alloy processed by liquid die forging were investigated. It is found that the grain size of the primary Si was significantly reduced by liquid die forging with increased pressure. The volume fraction of eutectic silicon was decreased with increased pressure. By liquid die forging with pressure up to 180 MPa, the average size of the primary Si was reduced to about 18 μm, which results in the remarkable increase in the fracture strength and hardness of the hypereutectic Al-Si alloy.
