The effect of dopants, rolling amount, annealing temperature and texture on the production of molybdenum single crystals by secondary recrystallization was investigated systematically. Secondary recrystallization of every doped specimen occurred at a temperature higher than 2100℃ In the case of the specimen doped with Ca(OH)₂, single crystals were made at the lowest temperature of 2100℃ In the specimens doped with Mg(OH)₂ and MgO rolled to 95%, however, single crystals were not made when annealed at 2100℃ and 2200℃ , respectively. The orientation of textures of rolling and primary recrystallization was {100}(hkl). The orientation of the single crystal deviated from {100}$lt;hkl$gt; by 1020°. |
