Abstract
The angular distributions of large-angle grain boundaries were studied by electron microscopy for Bi(2:2:1:2) and Bi(2:2:2:3) composite tape s. For Bi(2:2:2:3) the distributions are random, while for Bi(2:2:1:2) , there was a high incidence of special boundary misorientations. The preferred orientations in Bi(2:2:1:2), which were analyzed for [001] a nd [100] rotations, agreed well with the calculated lattice coincidenc es based on the constraint Coincidence Site Lattice model, and were at tributed to the reorientation of the neighboring grains during its par tial melt process.
