摘要: Nanocrystallization of CuNiTiZr bulk metallic glass (BMG) subjected to kinetic spraying with variable impact velocities was investigated through numerical and experimental approaches. The fraction crystallization activation energy the initial feedstock as-deposited coatings were estimated differential scanning calorimetry Kissinger method, respectively. results showed that crystallinity for nucleation in BMG is strongly related impacting particles. Upon high-velocity impact, particle led a decrease free barrier an increase driving force amorphous-to-crystalline phase transformation. Microstructure observation revealed nanocrystallization spray process associated strain delivered by plastic deformation using high rate.
