Figure 5. Serial No. London B 64— Scaling behaviour has been observed at mesoscopic level irrespective of crystal structure, type of boundary and operative micro-mechanisms like slip and twinning. The cleavage strength of polycrystals. In addition to misorientation, scaling behaviour was also observed for the cell size in deformed FCC metals 13 Introduction 3.

This can be attributed to the multiplicative nature of the various dislocation processes operative during plastic deformation. Grain Boundaries and Crystalline Plasticity ISTE It is well established that dislocations act as the carriers of plasticity and their gradual interaction with each other leads to work hardening that aids in avoiding early fracture in crystalline materials. National Center for Biotechnology InformationU. Some critical issues pertaining to deformation texture evolution in close-packed metals and alloys: The effect of grain size, strain rate and second phase. Recently, Chen et al. Nanostructured metals: Less is more.

This book explores the fundamental role of grain boundaries in the plasticity of crystalline materials, providing a multi-scale approach to plasticity to facilitate. Keywords: intergranular stress corrosion cracking, crystal plasticity, grain boundary, oxygen reaction-diffusion equation, crack propagation. based on the coupling between dislocation density-based crystal plasticity and phase derstanding the mechanisms and driving forces for grain boundary migration is of each grid point are obtained from an external file.

Intergranular fracture induced by liquid metals 6. Description Table of contents. We have shown that the scaling of misorientation distribution is inherent of any deformation process irrespective of the ability of the material to form cell structure and is applicable to both IDBs and GNBs at the meso-scale. The effect of strain on misorientation distribution as seen in Fig.

Titanium samples were obtained in different orientations along the longitudinal, transverse and normal direction from a rolled block of titanium with a strong basal texture to obtain samples with different initial texture.
