摘要: Abstract The blocking effect on grain boundary sliding of second phase particles is formulated by the inclusion method. From energy consideration, internal stresses produced which oppose are derived. usual relaxation modified and reductions strength time obtained. With additional consideration diffusional accommodation blocked diffusion around particles, an expression similar to those obtained previously recovered for effective viscosity at high temperatures. Comparison theories with experiment in a Cu-SiO2 alloy has been made. Internal friction bamboo structured specimen also considered when boundaries contain particles.
