摘要：Parameters of Bingham model had been verified according to the thermal simulation compression tests of semi-solid 6061 aluminum and the equations presented by Stefan. The effects of the mold filling temperature of semi-solid slurry of 6061 aluminum during thixo-diecasting were analyzed. The results showed that such conditions of the mold filling temperature about 625°C, the injection speed changing to 2 m/s from 0.4 m/s when 60% of die cavity had been filled, were ideal to gain solidification in sequence and beneficial to get fully filled semi-solid parts with clear contour. The thixo-diecasting experiments were performed under above optimized conditions. ? (2012) Trans Tech Publications, Switzerland.
