- Summary, etc.
- The temperature range of semi-solid zone and the rate of increase in strength in the zone were empirically determined on a series of Al-Si, Al-Cu, Al-Mg and Al-Zn alloys, and their relation to the tendency of hot tearing was discussed. The results indicate that the temperature range of the semi-solid zone well agreed with the length of cracks of casting in Al-Si, Al-Cu and Al-Zn alloys, and in the case of the first two alloys the maximum values of the semi-solid temperature range and length of cracks were observed at the limit of solubility of non-equilibrium diagram, which was determined by this experiment. The length of cracks of Al-Mg alloys were affected by the rate of increase in strength rather than by the semi-solid temperature range. The low susceptibility to the hot tearing in Al-Mg alloy system is believed to be in the great increase in strength in the semi-solid zone. Thus, the hot tearing of aluminum alloys are mostly interpreted in terms of the semi-solid zone and increase in strength in the zone.
