Microstructure and Properties of Semi-Solid CuSn10P1 Alloy under Different Filling Velocity by Squeeze Casting
Semi-solid CuSn10P1 alloy slurry was fabricated by a novel enclosed cooling slope channel (for short ECSC). The effect of filling velocity on microstructure and properties by squeeze casting was studied. The results showed that primary α-Cu phase gradually formed from dendrites evolved into worm-like or equiaxed crystals by ECSC. As the filling velocity increases, the ultimate tensile strengths and elongations of the shaft sleeve increase first and then decrease. The ultimate tensile strength and elongation of semi-solid squeeze casting CuSn10P1 alloy reached a maximum of 417.6MPa and 12.6% when the forming pressure is 100MPa and filling velocity is 21mm/s, which were improved by 22% and 93%, respectively, as compared to that of liquid squeeze casting.
