Abstract:

THIS PROGRAM WAS CONDUCTED TO OBTAIN ADDITIONAL CREEP DATA, TO COMP RE CREEP DATA FROM SEVERAL SOURCES AND TO RECOMMEND WHAT VALUES TO PRESENT AND IN WHAT FORM TO PRESENT CREEP DATA FOR DESIGN PURPOSES. Conventional long time creep tests were perform d on A- AT and 1500 ALLOAT at 800 an 100 and Unimach 2 t 0 nd 900 F for purposes of comparing with existing similar data. Conventional creep tests were performed on Rene 41 at 1250, 1400, 1550, 1700, 1850, and 20 F Data are presented in the form of activation series equations. Nomographs were derive for each material. Cyclic creep tests were performed on Rene 41, in which both stress and temperature were cycled. Cyclic data w re found to be comparable to the constant stress constant temperature data.
