Most of such dendrite cores are distributed in the grains with an elliptical morphology; some of them lie in the grain boundaries with triangular or lathy morphologies. There are few dislocations and substructures in the dendrite cores, and there are clear phase boundaries between such dendrite cores and the matrix.
Ni合金过冷熔体中亚稳相和稳定相的竞争形核的计算与实验结果定性吻合，即当熔体过冷度大于某一临界过冷度时亚稳相将作为初生相从过冷熔体中析出，通过分析发现瞬态形核理论能更好的描述深过冷熔体中的竞争形核问题。

The Bengtsson-Jacobson conjecture that "degenerate phase boundaries are always null" is studied by the mapping language in Chapter 4. By distinguishing a "phase boundary" from its image in the "covariant approach", the nulless of the image is proved. Time-like and null hypersurfaces in the degenerate space-times in the Ashtekar theory are denned, and then the phase boundary obtained by the "covariant approach" is shown to be always null.
我们在第四章用映射的语言分析了Bengtsson和Jacobson关于&相边界为类光&的猜想；通过区分&协变方法&中的&相边界&和它的像，我们证明了像的类光性；在定义了Ashtekar退化时空中的类时和类光超曲面之后，我们证明了&协变方法&得到的相边界必定是类光的。

The results show that Mg segregates to the phase bounda-ries of MC/γand γ′/γ. The thickness of Mg on MC/γ phase boundaries is latgerthan that on γ′/γ phase boundaries. The results prove that Mg is not only a grainboundary segregation element, but also a phase boundary searegation one.
结果表明，微量Mg偏析于MC和γ′相界面，而在其内部没有富集；Mg在MC相界面上的偏析厚度大于在γ′相界面的偏析厚度；试验结果及理论分析表明，Mg不仅是晶界偏析元素，更重要的是相界偏析元素。
