本文研究了强磁场对二元共晶合金初生相和共晶相取向的影响及其相互关系。在0 T时，亚共晶Mn-Sb中初生MnSb相呈随机取向，但在3、6、9和11.5 T时，其c轴垂直于磁场方向。在所有情况下，共晶MnSb相都表现出与其相邻的初级MnSb相相同的取向，它们在初级MnSb相上成核和生长。在强磁场作用下，共晶和初生MnSb相的c轴垂直于磁场方向。结果表明，在凝固过程中施加强磁场是控制共晶合金初生相和共晶相结晶取向的一种方法。
This paper investigates how applying high magnetic fields influences the crystallographic orientations of the primary and eutectic phases, and their relationship, in a binary eutectic alloy. At 0 T, the primary MnSb phase in hypoeutectic Mn–Sb showed a random orientation, but at 3, 6, 9 and 11.5 T, its c axis was perpendicular to the magnetic field direction. In all cases, the eutectic MnSb phases showed the same orientations as their neighboring primary MnSb phase, on which they nucleated and grew. With high magnetic fields, the c axes of the eutectic and primary MnSb phases were oriented perpendicular to the magnetic field direction. The results show that applying a high magnetic field during solidification is a way of controlling the crystallographic orientation of both the primary and the eutectic phases in eutectic alloys.
