AN INTERNAL FRICTION PEAK DUE TO HYDROGEN-DISLOCATION INTERACTION IN NICKEL

Abstract
Effects of hydrogen on the internal friction in deformed Ni are investigated at a frequency of about 30kHz. A relaxation peak develops after hydrogen charging at the expense of another relaxation peak induced by deformation, but it decays on subsequent ageing (outgassing). A simplified description of the cold-work peak which takes into account a nonuniform distribution of hydrogen in a specimen explains well the observed behaviour of this peak.
