Research on Segregation at Interface in Al_2O_(3f) /Al 4%Cu Alloy Composites
Al 2O 3f /Al 4%Cu alloy composites are manufactured by squeeze casting.Segregation at interface in the composites is researched.The results indicate that at the end of solidification of the composites,the change of the solute in the surplus liquid phase results in the type of matrix alloy being changed because of the selecting crystallization,and the segregation at interface is finally formed.There may be the dual effect of the segregation on structures and property of the composites.
