The microstructure of Tb0.27Dy0.73Fe1.8 with ordered plate-like structure, unordered cylindrical structure and mixed structure can be formed under different solidification conditions. For Tb0.27Dy0.73Fe1.95 alloy, however, the microstructure is always of ordered plate-like structure, independent of the temperature gradient GL and the crystal growth velocity V. The relationship between the solidification condition, the crystal morphology and the preferred growth direction of Tb0.27Dy0.73Fe1.95 alloy is analyzed. When the crystal morphology is cellular or non-branch dendritic, <110> orientation is preferred. A <112> orientation will be preferred when the crystal morphology is advanced dendritic, and when the crystal morphology is in the transition zone of cellular to dendrite, mixed orientations with <110>, <112> and <113> can occur. The cellular to dendrite transition zone is reduced with the increase of the temperature gradient. The solidification point GL/V is in the range of (9.60～10.45)×102 K·s/mm2 when the crystal morphology transits from cellular to dendrite., authors=null, authorsList=null, authorCompany=null,

at％)合金在不同凝固条件下的凝固行为。发现Tb0.27Dy0.73Fe1.8合金在不同的凝固条件范围内可以有有序的层状结构、无序的短柱状结构和混合结构，而Tb0.27Dy0.73Fe1.95合金的显微结构始终是层片状结构，在实验条件范围内与凝固条件无关；分析了Tb0.27Dy0.73Fe1.95合金定向凝固条件、晶体生长形貌、晶体择优生长方向间的关系，发现结晶形貌为胞状晶或无侧向分枝的树枝晶时其择优取向为<110>，结晶形貌为发达的树枝晶时其择优生长方向为<112>，而在胞-枝转变区晶体为<110>，<112>，<113>等多种取向的混合，胞枝转变区随温度梯度的提高而减小；Tb0.27Dy0.73Fe1.95合金定向凝固时发生胞枝转变的凝固条件为GL/V值介于(9.60～10.45)×102 K·s/mm2之间。, authors=周美政,季诚昌,朱世根, authorsList=周美政;季诚昌;朱世根, authorCompany=东华大学材料科学与工程学院 上海, correspAuthors=null, authorNote=null, correspAuthorsNote=周美政, copyrightStatement=null, copyrightOwner=null,
