摘要：
Friction stir processing (FSP) has been applied to incorporate 5-10 vol.% nano-sized SiO2 into an AZ61Mg alloy matrix to form bulk composites. The nano-particles were uniformly dispersed after four FSP passes, and the average grain sizes of the composites varied within 0.5-2 mu m. The composites nearly doubled the hardness of the base material and exhibited high strain rate superplasticity. (c) 2006 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
