Fe Ni 48 (supra - 50): magnetic annealing
Fe Ni 48 (supra - 50): magnetic annealing
(OP)
Hi guys,
just a simple question: during the magnetic annealing of Fe-Ni 48, Do I have to expect some dimensionnal variation on thin laminations (heat treatment at 1100°C under controlled atmosphere).
I'd like to know if I need to adapted the tooling to prevent a deformation of the lamination (I need extreme precision). Is the secondary cristallisation of such alloy a problem from a dimensionnal point of view? I don't find any clues on this point...

In fact, we use these laminations in stack, and we have a very tight tolerances on the inner diameter (35 mm diameter). What kind of dimensionnal variation should I expect on such diameter, for a Magnetic annealing (1100°C) and oxydation.
I will check the tolerances with our mechanical design, but to validate the treatment, I'd like to know what range of dimensionnal change I should expect.
Many thanks for your help!
