详细研究了Al-Mg2Si中NiAl3共晶组织的二维和三维形貌特征。研究发现，在共晶组织演变过程中，共晶NiAl3由粗大的不规则形状转变为细小规则的棒状，并与(AlCMg2Si)二元共晶有关。通过对形核和生长规律的详细微观观察，对其形貌变化的原因进行了讨论和分析。
Two- and three-dimensional morphological features of eutectic NiAl3 in Al-Mg2Si were studied in detail. It is found that eutectic NiAl3 transforms from enormous irregular shapes to fine regular rods, and the transition is related to (AlCMg2Si) binary eutectic during the process of eutectic structural evolution. The explanation about the morphological change was discussed and analyzed in terms of the detailed microstructural observation of nucleation and growth patterns.
