Texture and Grain Growth in Nanocrystalline Permalloy
The texture evolution accompanied by grain growth was investigated in a nanocrystalline Fe-78wt%Ni alloy, namely permalloy fabricated by using an electrodeposition method. The as-deposited specimen revealed a strong <100>//ND and a weak <111>//ND fibre-type textures. Grain growth took place during annealing beyond 370°C and resulted in the texture change such that the <111>//ND fibre strongly d...
متن کاملMicrostructure and grain growth of nanosized materials
An anomalous dependence of the lattice parameter on the crystallite size of nanocrystalline ball-milled powders of metals was observed: lattice contraction followed by lattice expansion with decreasing crystallite size. These data were determined by application of detailed Xray diffraction measurements. To this end, the lattice parameters of all the metals were accurately determined by correcti...
متن کاملAbnormal Grain Growth and Texture Development
A theory for abnormal grain growth (AGG) in polycrystalline materials is revisited and extended in order to predict AGG in textured polycrystals. The motivation for the work is to improve our understanding of the origins of the Goss texture component, {110}<001>, during annealing of Fe-Si sheet. Since the AGG phenomenon in grain-oriented electrical steels is known to be dependent on the presenc...
متن کاملThermodynamics of microstructure evolution: grain growth
It is gradually getting clear that the macroscopic description of microstructure evolution requires additional thermodynamic parameters, entropy of microstructure and temperature of microstructure. It was claimed that there is "one more law of thermodynamics": entropy of microstructure must decay in isolated thermodynamic stable systems. Such behavior is opposite to that of thermodynamic entrop...
متن کاملNanoindentation Induced Deformation Near Grain Boundaries of Corrosion Resistant Nickel Alloys Citation
The damage accumulation behavior of different grain boundary structures in Inconel 690 (Ni-29wt%Cr-9wt%Fe) was investigated in the presence of large, localized plastic strains induced by nanoindentation. Spatially-resolved hardness was measured as a function of lateral distance from ‘random’ high-angle grain boundaries and twin boundaries. The confinement of induced defects between the indenter...
