Mn-89.7wt.%对Sb合金试样在不同磁场中进行了不同保温时间的凝固试验。研究了强磁场对合金中初生和共晶MnSb晶体取向以及初生MnSb晶粒排列的影响。结果表明，在强磁场作用下，初生MnSb晶体的c面平行于外加磁场方向取向，而共晶MnSb合金中的共晶MnSb不能被强磁场取向。初生MnSb枝晶沿着磁场方向排列。这种取向是晶体取向、晶体生长特征和热流共同作用的结果。
Mn–89.7wt.%Sb alloy specimens were solidified in various magnetic fields with different holding times. The influence of the high magnetic field on the orientation of both the primary and eutectic MnSb crystals and on the alignment of the primary MnSb grains in the alloys has been investigated. It was found that the primary MnSb crystals were oriented with their c-plane parallel to the imposed magnetic field direction, but the eutectic MnSb from a eutectic MnSb alloy could not be oriented by the high magnetic field. The primary MnSb dendrites were aligned along the magnetic field direction. This alignment may be attributed to combined effects of crystal orientation, crystal growth feature and heat flow.
