Creep and High Temperature Plasticity: Grain Boundary Dynamics 330 $aThis book explores the fundamental role of grain boundaries in the plasticity of crystalline materials, providing a multi-scale approach to plasticity to facilitate understanding. It starts with the atomic description of a grain boundary, moves on to the elemental interaction processes between dislocations and grain boundaries, and finally shows how the microscopic phenomena influence the macroscopic behaviors and constitutive laws. Drawing on topics from physical, chemical, and mechanical disciplines, this work also explains properties of deformation at low and high temperature, creep, fatigu 410 0$aISTE 606 $aGrain boundaries$xMathematical models 606 $aCrystalline interfaces 606 $aDislocations in crystals 615 0$aGrain boundaries$xMathematical models. 615 0$aCrystalline interfaces. 615 0$aDislocations in crystals. 676 $a660/.284298 701 $aPriester$b Louisette$0922602 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910821368303321 996 $aGrain boundaries and crystalline plasticity$93983002 997 $aUNINA
