摘要：
Grain growth in the textureless material characterized by bimodal grain size distribution has been investigated. Grain growth in a pure material can eliminate the second maximum in the distribution, despite the presence of abnormally coarse crystallites in the initial structure. This is true when the number of coarse crystallites in the initial state is small and can be explained by normal grain growth in the fine-grained matrix. The size effect of matrix grains on the second maximum in the distribution under these conditions has been analyzed. The second maximum has been shown to remain and even increase due to the inhibition of boun-dary migration.
