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.軽金属学会2004jpnjournal articleVoRhttp://hdl.handle.net/2115/75093https://doi.org/10.2464/jilm.54.522100140335250451-59941880-8018AN00069773軽金属Journal of Japan Institute of Light Metals5411522526https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/75093/1/Journal%20of%20Japan%20Institute%20of%20Light%20Metals%2c%20Vol.%2054%2c%20No.%2011%20%282004%29%2c%20pp.%20522-526.pdfapplication/pdf1.6 MB2004
