本文提出了一种大尺寸比非均匀二元粉末混合物烧结的几何模型。该模型被证明是一个假设的混合物中的异质性描述的正态分布函数。该模型被证明的情况下，细分数烧结和两个组件烧结的情况下。相对于均匀混合物的预测，收缩被观察到是“增强”，“延迟”，或相同的，这取决于非均匀性的组成限制和烧结的水平。
A geometric model for the sintering of inhomogeneous, binary powder mixtures having a large size ratio is presented. The model is demonstrated for a hypothetical mixture in which the heterogeneity is described by a normal distribution function. The model is demonstrated for the case of the fine fraction sintering only and for the case of both components sintering. Relative to the prediction for the homogeneous mixture, shrinkage is observed to be either “enhanced,”“retarded,” or the same, depending on the compositional limits of heterogeneity and the level of sintering.
