The recrystallization temperature for cast rhenium is lower than for the metallo-ceramic rhenium. The data show that rhenium does not have tendencies to sudden grain growth even at annealing temperatures as high as 2000 to 3400 deg . The grain diameters of rhenium deformed by various degrees of compression higher than critical do not exceed 15 to 20 mu for metalloceramic rhenium amd 100 mu for cast rhenium. The high hardening property of rhenium calls for frequent intermediate annealing during cold treatment. The optical temperature for rhenium annealing with more than 10% deformation was found to be in the range of 1750 to 2400 deg . (R.V.J.)
