Hot deformation behavior and microstructural evolution of particulate-reinforced AA6061/B4C composite during compression at elevated temperature
TL;DR: In this article, the effects of Z values on dynamic softening and associated microstructural evolution during hot deformation were investigated by electron back scattered diffraction technique (EBSD), which indicated that the main softening mechanism of AA6061/B4C composites was dynamic recrystallization (DRX).
Journal ArticleDOI
Stability of the Al/TiB 2 interface and doping effects of Mg/Si
TL;DR: In this paper, the interfacial energies were investigated by first-principles calculations, and the results support the reported grain refinement mechanisms in Al/Si alloys and showed that the two interfaces will both weaken after doping Mg/Si, thus the formation of TiB2 is inhibited.
