A. Ramesh et al., HYDROGEN CHARGING IN NICKEL AND IRON AND ITS EFFECT ON THEIR MAGNETIC-PROPERTIES, Journal of applied physics, 79(8), 1996, pp. 5453-5455
The current study was undertaken to explore the possibility of detecti
ng hydrogen cavitation in magnetic materials through magnetic property
measurements. It is known that dissolved hydrogen in a material cause
s microvoids. These voids may affect the structure-sensitive magnetic
properties such as coercivity and remanence. In this study, hydrogen w
as introduced into nickel and iron by two processes, namely thermal ch
arging and cathodic charging. The effect on the magnetic properties wa
s measured. In addition, the variation of the magnetic properties with
porosity was studied. (C) 1996 American Institute of Physics.
