Abstract:

An X-ray diffraction survey was made of preferred orientations developed in high purity aluminum, copper, iron, and magnesium during rolling at elevated temperatures. Variables studied were the effects of rolling temperature and the duration of intermediate annealing times between roll passes. Aluminum was rolled to 90 reduction in 10 increments at 237, 316, and 402 C copper at 150, 200, and 421 C iron at 600 and 732 C and magnesium at 204, 316, and 427 C. The intermediate annealing times used were 10 and 310 seconds. Iron warm rolled at 600 C has a preferred orientation that may be described by rotational scatter of the 100 011 major component about the 011 direction and a 111 112 minor component. Increasing the rolling temperature to 732 C results in elimination of the 111 112 minor component. Author
