摘要： 考虑不规则夹杂物对针状铁素体形核的影响，建立了基底相、析出相均为正三棱锥形的形核数学模型。通过理论分析发现：可诱发铁素体形核的夹杂物不仅为球形，也可为不规则带有棱角的夹杂物；夹杂物与铁素体之间的润湿角越小，夹杂物越容易诱发针状铁素体形核；基底相侧面顶角ω在75°～120°时，不规则夹杂物易诱发针状铁素体形核。

Abstract: In consideration of the influence of irregular inclusions to the nucleation of acicular ferrite, building the nucleation model whose base phase and precipitated phase are normal triple prism. Theoretical analysis reveals that not only spherical inclusions can induce acicular ferrite to nucleation, but also irregular inclusions with corner angle. The smaller of the wetting angle, the easier of the acicular ferrite to nucleation. When the side corner of the base phase is between 75°－120°, the irregular inclusions induce the acicular ferrite to nucleation easily.
