Abstract:	Hydrogen-induced phases, relaxation and hysteretic phenomena in Fe₅₅Cr₂₅Ni₂₀ and Fe₅₀Ni₅₀ alloys were studied using neutron scattering and internal friction. Substitution of chromium by nickel prevents the hydrogen-induced γ→ transformation, which was used for interpretation of the IF peaks. A new relaxation peak is observed in the hydrogen-charged Fe₅₀Ni₅₀ alloy.
