Abstract:
The importance of using fatigue data for the selection of structural materials and the design of aerospace systems has been well recognized in recent years. It is the purpose of this program to obtain axial fatigue data and fill some of these more critical areas by supplying S-N curves and Goodman Diagrams. The program will obtain axial loading fatigue data for several alloys -- AM 350, 17-7 PH, and PH 15-7 Mo -- at room and elevated temperature in the unnotched and notched conditions. In addition, limited tensile and stress rupture data to complement the fatigue data will be obtained. The AM 350 SCT, 17-7 PH RH 950, and PH 15-7 Mo RH 950 materials have been heat treated and specimens are now being machined. The sheet material which is to be heat treated at 1050 F is being heat treated. The four inch square billet forging has had the outside surfaces machined to remove scale and contamination. The billet is being cut into blanks which will be heat treated and machined into specimens.
