%X Crystallography of phase transformation is used as the main principal to guide Mg-Sn-X alloy design. Based on a comprehensive literature survey, two criteria of crystallography of phase transformation are given to select the precipitate probably growing along 0001]α direction of Mg matrix. Combined with available data of phase diagram, we deduce that β-Mn in Mg-Sn-Mn system is a hopeful candidate. TEM study on the specimen of Mg-7.5Sn-2.2Mn (mass fraction, %) alloy confirms that rod-like β-Mn precipitates grow along 0001]α, and their orientation relationship (OR) with Mg matrix is 0001]α///211]β-Mn, 0110]α///011]β-Mn, 2110]α//111]β-Mn.
