The microstructure and orientation relationships of ZK60A magnesium alloy matrix composite reinforced with SiC whiskers and B4C particles have been studied by means of transmission electron microscopy and high-resolution electron microscopy. MgO nanocrystalline particles are formed at SiC/Mg interfaces with a cube-on-cube orientation relationship with SiC whiskers. MgB2 nanorods are formed near the B4C particles. Two types of orientation relationships between the SiC whisker and Mg are observed, which are [(1) over bar 11](Sic) parallel to 1 [0001]Mg and (02 (21) over tilde)(Sic) parallel to(11 (2) over bar0)(Mg), and [(1) over bar 11](SiC)parallel to[11 (2) over bar0](Mg) and (02 (2) over bar)(SiC)parallel to (0 112),,,,,,. Geometrically, [(1) over bar 11](SiC)parallel to [0001]Mg and (02 (2) over bar)(SiC)parallel to (01 (1) over bar0)Mg is more favorable than [I I I]sjCjj and (02 (2) over bar)(SiC)parallel to (01 (1) over bar2)(Mg).
