抄録

Alumina short fiber/magnesium alloy matrix composites were fabricated by using a squeeze casting method. In this study, Mg-4%Zn alloy was selected as a matrix alloy because it has high thermal conductivity. Rare-earth elements were added to the Mg-4%Zn alloy as a third alloying element which is useful for improvement of high temperature strength. The effects of additions of 1%Nd and 1%Ce on structures and mechanical properties of the composites were investigated. RE elements in the liquid react with SiO₂ additives of alumina short fiber, and form needle shaped compounds consisted of Si and RE on the surface of fiber. Tensile strength of the composites at room temperature increases by both an addition of RE element and heat treatment. Nd has the highest contribution for an increase in strength among light rare earth elements. Tensile strength of the composites at 250°C depends only on fiber volume fraction and neither on the addition of RE elements and nor on heat treatment.
