The complex interplay between energetic and kinetic factors that governs the phase morphology selections can originate at earliest stage of crystallization in amorphous parent phases. Because extreme difficulties capturing microscopic nucleation process, a detailed picture how initial disordered structures affect transformation pathway remains unclear. Here, we report experimental observation w...

r(NJ Nucleation rates in condensed systems are frequently not at their steady state values. Such time dependent (or transient) nucleation is most clearly observed in devitrification studies of metallic and silicate glasses. The origin of transient nucleation and its role in the formation and stability of desired phases and microstructures are discussed. Numerical models of nucleation in isother...

Abstract Bulk metallic glass of Cu 38 Zr 54 Al 8 nominal composition was synthesized by copper mold casting into 6 mm diameter rods. Disks the as-cast were subjected to severe plastic deformation high-pressure torsion for different number revolutions. The microstructure and thermal behavior as-cast, isothermally annealed deformed have been investigated X-ray diffraction differential scanning ca...
