Abstract
The effect of hydrogenation on the mechanical and magnetic response of amorphous Fe73.5Nb3Cu1Si13.5B 9 alloys was studied. Hydrogen was charged electrochemically by varying charging current density. Magnetic Barkhausen emissions and coercivity were measured in charged and degassed samples. It was found that both responses were reversible. The hydrogen induced stress was responsible for these reversible effects. The kinetics of hydrogenation and of degassing are reported. © 2003 Elsevier Science B.V. All rights reserved.
