Fiber reinforced magnesium alloy.

摘要

A composite material having heat resistance at elevated temperatures and excellent mechanical properties to be used for parts of automotive vehicles, especially for pistons, machine parts or aerospace materials is composed of fiber reinforced magnesium alloy as a matrix having a composition of magnesium alloy containing up to 2 to 15 wt%, but preferably 4 to 7 wt% of neodymium or corresponding amount of neodymium-type metals, for example, didymium containing at least 70 wt% of neodymium. The composite material is composed of 70 to 95 vol% of the matrix and 30 to 5 vol% of short alumina fibers as the reinforcement.
