Abstract : To obtain comparative fatigue test data on three sheet materials selected for possible use on supersonic transports, a multi-phase program of tests was carried out using speciments of duplex annealed 8-1-1 titanium, PH14-8 Mo (SRH 1050) stainless steel and Inco 718 alloy in the 20% cold rolled and aged condition. Unnotched, centernotched, fusion-welded and spotwelded specimens were used. Constant load amplitude (S-N) fatigue tests were conducted at room temperature, 400 and 650 F on specimens having no prior exposure and on specimens with prior exposure to a constant load at 400 or 650 F for 100, 1000 or 5000 hours. An evaluation was also made of the effect of applying contaminants during S-N testing at 550 and 650 F to specimens having no prior exposure and to specimens exposed to load and contaminant at 550 F for 1000 hours.
