A novel two-step method to prepare fine-grained SiC/Al-Mg-Sc-Zr nanocomposite: Processing, microstructure and mechanical properties

In this study, a novel two-step method consisting of powder metallurgy (PM) and subsequent friction stir processing (FSP) was used for preparing SiC/Al-Mg-Sc-Zr nanocomposites integrating multiple beneficial microstructural factors, including high densification, uniform distribution of SiC nanoparti...
