Effect of temperature on the fatigue-crack propagation behavior of A-286 steel

PDF Version Also Available for Download.

Description

The techniques of linear-elastic fracture mechanics were used to characterize the effect of temperature upon the fatigue-crack growth behavior of A-286 steel in an air environment over the temperature range of 75--1000$sup 0$F. In general, the fatigue-crack growth rate increased with increasing temperature. Two material forms were tested: 0.5 inch-thick strip material and 1.5 inch- diameter bar. Two different crack orientations were tested in each product form. In general, no significant differences in crack growth behavior were noted between product forms nor between the different crack orientations. (auth)
