Description
An electron channeling study has been done on large grained YBa2Cu3O/sub x/ samples. Selected area channeling patterns (SACP) were used to examine several dozen grains on electropolished surfaces and it was demonstrated that (a) the twin planes observed in polarized optical light microscopy lie parallel to /110/ crystal planes, and (b) the long flat sides of high aspect ratio grains are formed by basal planes, and the shorter sides are formed by either (010), (100), or /110/ planes. A majority of the large grains examined were found to contain subgrains, misaligned by 0.50--10 and ranging in size from less than 3 to 20 μm. The origin of the subgrains is not understood
