INVESTIGATION OF AXIAL LOADING FATIGUE PROPERTIES OF HEAT-RESISTANT ALLOY N-155

Abstract

Dynamic creep and rupture data are presented on N-l55 at room temperature and 1000 F, correlated to some extent with prior work. Temperature increases were observed in certain temperature and stress ranges immediately after the application of alternating stress to a test specimen. These are discussed in terms of the internal damping capacity of the material and the possibility of utilizing these observed temperature increases as a qualitative indication of damping is suggested. A vibration analysis of the Minnesota direct stress fatigue machine is presented and used to correlate calibration data procured by three independant methods.
