Historical publication digitized from print 2017 [by Natural Resources Canada]. Includes bibliographical references. "Two commercial aluminum alloys were cyclically stressed in moist and dry air. The data obtained give substantial support to the hypothesis that variable cracking of the surface oxide is responsible for environmental fatigue effects. Processing in kerosene was found to have differing effects on the two alloys. A polar organic compound added to kerosene produced a significant reduction in the scatter of data from one alloy"--Abstract, p. 1. gccst Metals gccst Physics Thurston, R. C. A. Canada.
