Quantitated heterogeneity of serrated flow and the microstructural analysis in stirred zone

Friction stir processing (FSP) was applied to Al–Mg-Sc alloy, and the local difference of microstructure in stirred zone (SZ) resulted in the change of serrated flow. By the statistics and the quantitative analysis based on multifractal theory, a general framework on the time structure of stress dis...
