| Abstract: | Hot cracking experiments were carried out for Al 0 6wt%Cu and Al 2 0wt%Cu alloys in directional solidification device under different furnace temperature.The hot cracking fendency of Al Cu alloys was evaluated in a semi quantative method.With measurement of cooling curves in directional solidification process,the formation of hot cracks in solidification process was theoretically analysed.It was discovered that hot cracking tendency of directionally solidified Al Cu alloys corresponds with their uncompensated distance under different furnace temperature. |
