Abstract
A magnesium base composite material is provided such that compound particles generated by a solid-phase reaction with magnesium are uniformly dispersed in a magnesium alloy body. The compound particles dispersed in the body comprise magnesium silicide (Mg2Si) and magnesium oxide (MgO) so that the magnesium base composite material may have excellent strength, hardness and abrasion resistance and tempered opponent aggression.

A method of manufacturing a structural component material comprising a magnesium base composite material, comprising:
- a step of providing a mixture by mixing a first material comprising magnesium and a second material containing a SiO2 component so as to comprise 2.5 to 12 parts by weight of the SiO2 component based on 100% by weight of the total of the first and second materials;
- a step of providing a pressed powder molded body by applying pressure to said mixture;
- and
- a step of heating said pressed powder molded body to 250° C. or more in an inert gas atmosphere or in vacuum to generate magnesium silicide (Mg2Si) and magnesium oxide (MgO) in a magnesium alloy body by a solid-phase reaction sintering between Mg and SiO2 in said pressed powder molded body.
