this preferred orientation. It is found that as directional solidification continues, the crystals with high growth speed remain and those with low growth speed vanish. The crystal preferred orientation tends to be <100>direction in competition growth process. Namely, the <100>fiber texture of Al-1.0%Si alloy rod becomes stronger in the stable directional solidification establishing process. When......
