Study on Microstructure Evolution and Liquid－Solid Correlation of Pur e Aluminum Melts
Year: 2000
Type: article
Abstract: The molecular dynamics simulations have been performed on microstructure and tra n sfer mechanism of liquid Al. The pair distributed function has been attained at different temperatures and cooling rates by means of tight－binding potential. T he proportions of small atom groups of different types have been analyzed by ado pting bond pair index method. The result indicates that if the cooling rate is l ow crystals will be formed otherwise amorphism will occur under relatively hi gh cooling rate. When the liquid Al forms crystal the bond pairs 1421 1422 play an important role while the pairs 1551 1541 have the close connection with the formation of amorphism.
