Enquiries were made into the technique of manufacturing sheet-like bicrystals and tricrystals of aluminium and columnar tricystals of zinc having the required orientations. (1) Bicrystals of the required orientations: First, a sample of the specific shape is carved out of aluminium sheet. Then a single crystal having either a crystallographic orientation common to the two crystals which is to consitute a bicrystal or the same orientation as one of these two crystals is produced from the sample using a Bridgeman’s furnace. Finally, the single crystal is subjected to an orientation conversion treatment using two seed crystals spontaneously developing a grain boundary. (2) Sheet-like tricrystals of the required orientations: A sample of the specific shape is carved out of aluminium sheet, and subjected to a treatment similar to the above-mentioned case of bicrystals. (3) Columnar tricrystals of the required orientations: Three seed crystals are welded to the tips of sample of the proper shape, and after the seed crystals are twisted and bent so that their orientations may be brought in line with the required orientations, the sample is made into a tricrystal in a Bridgeman’s furnace. The deviation from the required orientations of the bicrystals and tricrystals thus manufactured was found to be in the vicinity of ±1°.
