An Eddy-Current Study of Decay of Oversaturated Solid Solution in N32T3 Invar

Summary:The eddy-current parameter fo has been studied as a function of temperature and aging time for the N32T3 Invar. Two initial states have been involved: those after quenching and after cold plastic deformation. The rise in the temperature and time of aging reduces the parameter f0 owing to the transition of the Invar from the ferromagnetic to paramagnetic state because the oversaturated solid solution decays, and the austenite is depleted of nickel. The parameter f0 drops monotonically with the applied strain. In the strained Invar the decay of the oversaturated solid solution reduces f0 in the temperature interval of 400 to 600 deg C.
