In particular, loading waves are designed so that the maximum tensile stress first appears in the grain interior for all the crystals with different …
WebJul 3, 2012 · This Letter addresses a new finding of the connection between the macroscopic fatigue cracking behaviors of twin boundaries (TBs) and the microscopic TB-dislocation interactions. According to the difference in crystallography beside TBs, slipping dislocations usually interact with TBs in different modes during plastic deformation. In …
WebMetals containing abundant coherent twin boundaries (TBs) are able to sustain substantial plastic deformation without fracture due to shear-induced TB migration and sliding. Retaining ductility in these metals, however, has proven difficult because detwinning rapidly exhausts TB migration mechanisms at large deformation, whereas TB sliding was only … max burns nbc newsWebRapid quenching of Al-Mg alloys during superplastic deformation has revealed the presence of nano-scale cavities along many grain boundaries. They were observed only under deformation conditions where grain boundary sliding was the dominant mechanism.
