Internal Friction Peak in FCC Fe-Cr-Ni Alloys Hydrogen-Charged by Gas-Equilibration Method

摘要

An internal friction peak due to hydrogen in Fe_(55)Cr_(45-x)Ni_x (x = 20-45) and Fe_(100-x)Ni_x (x = 35-100) alloys was observed. A gas-equilibration method was employed in order to charge specimens homogeneously with hydrogen. In Fe_(55)Cr_(45-x)Ni_x alloys, the peak height significantly increased as the nickel content increased, whereas in Fe_(100-x)Ni_x alloys the peak height did not show a monotonic change versus the increasing nickel content. In both alloys the peak height depended strongly on the alloy composition.
