WebSrolovitz et al. [566] suggested that incoherent particles have interfaces that may slip and can attract dislocations by reducing the total elastic strain energy. Thus, there is a detachment stress that reflects the increase in strain … WebAnalysis on grain boundaries revealed that the fraction of twin boundaries is quite low in both samples ...

WebJun 19, 2024 · Evidence suggests that the interfaces between crystals of the material – the grain boundaries – influence how materials will fail. This area has been the subject of Dr … WebMar 4, 2024 · Away from grain boundaries, some DPs grew along [220] direction, with a coherent interface at the front and semi-coherent interfaces on the long sides ... Thus, we assumed that the cap-shaped part had an incoherent Cu/Ag interface with a Cu grain on the opposite side of the boundary. Our STEM images showed that each cone-shaped part, on … onyx orton obituary

WebAbstract. Despite their wide presence in hcp metals, incoherent tilt grain boundaries (ITGBs) are rarely studied. In this work, first-principles calculations were combined with atomic … Webareas of grain boundaries as a function of lattice misori-entation and grain boundary plane orientation over the entire range of possibilities [10]. While in the current paper, it is the grain boundary line length per area that is measured, this quantity is stereologically related to the area per volume [11]. A significant challenge associated ... WebMay 1, 2015 · Ni-based fcc alloys are frequently used as critical structural materials in nuclear energy applications. Despite extensive studies, fundamental questions remain regarding point defect migration and solute segregation as a function of grain boundary character after irradiation. In this study, a coupled experimental and modeling approach is … onyx orton
