The contribution of grain boundary sliding to axial strain during diffusion creep

摘要: Abstract Grain boundary sliding is necessary during diffusion creep to maintain continuity across the grain boundaries. In this paper it shown, by use of a two-dimensional hexagonal array, that will contribute additional axial strain specimen as predicted R. N. Stevens (1971). It however, there difference between macroscopic effect type and ‘ordinary’ sliding, in former, named Lifshitz does not increase number grains along length specimen, whereas, latter, Rachinger does. Considering only creep, concluded where egb(L) due ed polycrystalline aggregate would experience if stress-directed were occur without which case separation occur, egb et...
