ELEVATED-TEMPERATURE COMBINED STRESS-RUPTURE PLUS FATIGUE STRENTH OF WASPALOY HAVING DIFFERENT AGING TREATMENTS AND/OR MOLYBDENUM CONTENTS
Technical Report
·
OSTI ID:4240948
Waspaloy was studied (at 1500 deg F) to determine if stress-rupture ductilities and notch sensitivities associated with given aging treatments and/or molybdenum contents could be correlated with respective combined stress-rupture plus fatigue strengths. A possible relation between stress-rupture ductility and combined stress-rupture plus fatigue strength was indicated. No clear relation was found bctween notch-rupture strength and combined stress-rupture plus fatigue strength. If heat treatment and/or composition alone are considered, results indicate that double aging could improve combined stress strength and that double aging plus increased molybdenum content could cause a further increase in combined stress strength of Waspaloy.
