Abstract : This report describes the results of a limited investigation to determine the effects of cold deformation and subsequent stress relieving or aging on the rotating-beam fatigue properties of HY-80 steel. The tests were run to determine whether sufficient variation in the low-cycle fatigue lives existed to warrant an extensive investigation of the effects of cold forming on the fatigue properties of HY-80 steel. The results indicated that no large changes took place in the rotating-beam fatigue lives of specimens that had been previously cold-deformed in tension or compression or of specimens that had been cold-deformed and subsequently stress-relieved or aged, especially when compared with expected changes in fatigue life resulting from notches, flaws, etc. (Author)
