Exploratory Thermal-mechanical Fatigue Results for Rene' 80 in Ultrahigh Vacuum
A limited study was conducted of the use of strainage partitioning for predicting the thermalmechanical fatigue life of cast nickel-base superalloy Rene' 80. The fatigue lives obtained by combined inphase thermal and mechanical strain cycling between 400 C (752 F) and 1000 C (1802 F) in an ultrahigh vacuum were considerably shorter than those represented by the four basic partitioned inelastic strainrange fatigue life relationships established previously for this alloy at 871 C (1600 F) and 1000 C (1832 F) in an ultrahigh vacuum. This behavior was attributed to the drastic decrease in ductility with decreasing temperature for this alloy. These results indicated that the prediction of the thermal-mechanical fatigue life of Rene' 80 by the method of strainrange partioning may be improved if based on the four basic fatigue life relationships determined at a lower temperature in the thermal-mechanical strain cycle
Bulk-sensitive Photoemission of Mn5Si3
We have carried out a bulk-sensitive high-resolution photoemission experiment
on Mn5Si3. The measurements are performed for both core level and valence band
states. The Mn core level spectra are deconvoluted into two components
corresponding to different crystallographic sites. The asymmetry of each
component is of noticeable magnitude. In contrast, the Si 2p spectrum shows a
simple Lorentzian shape with low asymmetry. The peaks of the valence band
spectrum correspond well to the peak positions predicted by the former band
calculation.Comment: To be published in: Solid State Communication
