Abstract
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.
