Three kinds of magnesium based titanium particles-dispersed functionally graded materials (FGMs) were fabricated by a centrifugal solid-particle method. Materials were pure magnesium, AZ91D (9.23Al–0.7Zn–0.028Si–0.23Mn–0.0019Fe–0.0014Cu–0.001Ni–0.0009Be–bal.Mg) and Mg–6 mass%Zn alloys. The specimen shape was cylinder with 15–20 mm in length. Microstructures of FGM specimens were observed using an optical microscopy (OM) or a scanning electron microscopy (SEM). 2 vol%Ti was added into Mg–6 mass%Zn by a vortex addition technique in order to fabricate Mg–6 mass%Zn–2 vol%Ti master alloy. It was found that a large number of titanium particles were observed in the outer region of the cylinder, since the titanium particles migrate to outer region during the centrifugal solid-particle method. In this way, the magnesium based titanium particles dispersed FGM can be successfully fabricated by the centrifugal solid-particle method. Moreover, Vickers hardness increases with increasing the amount of titanium particles.
