چکیده انگلیسی
Ultrafine-grained aluminum composites produced via cryomilling exhibited ultrahigh strength associated with considerable strain-to-failure (>14Â pct.) at high strain rates (>103Â sâ1), but only limited strain-to-failure (â¼0.75Â pct.) at quasi-static strain rates (10â3Â sâ1). The mechanisms leading to these differences in behavior were investigated by systematic microstructural analysis of deformed and pre-deformed samples. Micro-flaw developments, including kinking, extensive axial splitting, and grain growth, were observed after high strain rate deformation, and the significance of these mechanisms is considered.
