ABS>Thermal cycling tests in the temperature ranges 550 to 100 deg C, 630 to 100 deg C, and 630 to 400 deg C were made on alpha uranium tc study the effects on macro and microstructure. The cycling usually causes subgrain formation, grain boundary corrugation, and migration accompanied by intergranular deformations. These changes develop faster for the 630 to 100 deg C cycle because the internal stresses are stronger. Samples with ragged grain boundaries are more easily crushed than those with smooth grain boundaries. The double texture formed during thermal cycling is discussed, and a correlation between the grain size and the double texture is suggested. (auth)
