%X In situ eutectic Al_(11)La_3/Al composite material with regular arrangement was prepared byzone melt liquid metal cooling directionally solidification under conditions of high temperaturegradient G=700K/cm and growth rate R=6.0-20.0μm/s.Superpose diffraction pat-tern of Al_(11)La_3/Al composite shows that the preferred growth direction is100]Al//33]Al_(11)La_3,and the habit plane is(002)Al//(116)Al_(11)La_3.A low density(103)twin is ob-served in Al_(11)La_3 and the growth of(103)twin induces to branching to change theinterlamellar spacing.
