摘要：
Experimental and computer investigations were conducted to study the flow stress and grain refinement during equal channel angular (ECA) pressing of nanostructured samples and ingots. The results of these investigations are used to determine the most optimal conditions for practical application of ECA pressing and obtaining bulk uniform nanostructured ingots due to fitting of optimal friction conditions.
