Superdislocation dissociation in twist boundaries

In a recent paper low angle twist boundaries were observed in boron free and boron doped Ni-rich Ni sub 3 Al manufactured by hot pressing together Ni-24 at.% Al single crystals with {001} surfaces. As the misorientation angle increased so did the dissociation distance of the screw superpartials. Thi...
