Abstract

Grain Boundaries in two specimens of Ni4Al of different compositions and mechanical behavior were studied by electron microscopy. SEM was used to determine the distribution of Σ values in both samples. TEM results were combined with CSL theory to completely characterize the nature of the boundaries, including Σ values and the grain boundary plane orientation. The boundaries most commonly observed in the experiments were also studied using a computer simulation technique and the results correlated with the experimental observations.
