      Rutherfordα-particles backscattering technique was employed for measurements of diffusion rates in metallic glasses. Effects of relaxation, crystallization and plastic deformation on diffusion rates were also investigated.

      It has been observed that the diffusion rates of a metallic solute are of the same orders of magnitude in both metal-metal and metal-metalloid glasses. A higher diffusivity is likely if there is a large difference between melting points of the solute and matrix. Relaxation has no effect on diffusion, however, diffusivity increases on crystallization. An increase in diffusivity is also observed on plastic deformation of metallic glass.

      More Details Abstract Fulltext PDF

      Differential scanning calorimetry (DSC) technique has been employed to study the crystallization kinetics of a Fe74Co10B16 glass. Crystallization of Fe74Co10B16 glass is known to occur in two distinct stages. It was possible to separate out the isothermal kinetics of both the crystallization stages through a thermal treatment scheme in the DSC. The crystallization processes are interpreted in the light of the kinetic data obtained.
