【Abstract】 The solidification model of fiber reinforced binary aluminum alloy was established according to the conservation law and the transfer principle of alloy solidification. The numerical simulation of the solute transfer and the solute distribution was carried out on Al 2O 3/Al Cu composite by the established model. The effect of solute segregation during soldification of the composite on the fiber/matrix interface was studied. The calculated values coincide with the experimental results on the whole.更多还原
