ELEVATED TEMPERATURE FATIGUE PROPERTIES OF D6AC HIGH STRENGTH STEEL

Abstract

A program was conducted to obtain complete stress versus number of cycles (S-N) curves for D6AC steel heat treated to an ultimate strength of 270 KSI. Tension-tension fatigue tests were conducted on notched and unnotched specimens at 75, 450, and 550 F for stress ratios of 1 and infinity. Tensile and stress rupture data were obtained in conjunction with the fatigue data.
