Abstract

The unidirectional C_f/Mg composites were fabricated by a pressure infiltration method. The effect of hybrid SiC particle on microstructure, mechanical properties and thermal expansion coefficient (CTEs) of M40/ZM6 composites was investigated using scanning electron microscope (SEM), transmission electron microscope (TEM), electronic tensile testing machine and thermal expansion instrument. Results show that feathery NdSi₂ phase at SiC-ZM6 interface is formed. After carbon fiber is hybrid reinforced with SiC particles, NdSi₂ phase improves the wettability between reinforcements and magnesium alloys, which improves mechanical properties of composites and decreases their horizontal CTEs. CTEs of unidirectional carbon fiber is hybrid reinforced with SiC particle composites between 20 ℃ and 150 ℃ are in a good agreement with the model derived by the author.
