【Abstract】 According to the bond energy formula of the empirical electron theory of solids and molecules, the mechanism of order-disorder transformations is analysed from the results of the bond energy and the bond structures of the alloys. The Fe-Al binary alloys have an order-disorder transformation which is resulted in the change of numbers of covalent electron pair on bonds.更多还原
