| Abstract: | Undercooling up to 62K in a metal mold have been obtained for Al--4. 5%Cu alloy melt by superheating and denucleating with chloride flux. Based uPOn nucleation rate theory, the maximum thermodynand undercooling of Al--4.5 %Cu alloy nucleating on Al2O3has been calculated between 74K and 104K. |
