We succeeded in creating a partial nonmagnetic area in magnetic 0.65C-13Cr-Fe alloy. This 'dual state magnetic material' is expected to separate magnetic design from mechanical design for ideal magnetic parts. A material for automotive use must be able to withstand temperatures below -40 ℃. To use dual state magnetic material as an automotive part, it is necessary to find an appropriate method to obtain a steady state down to -40 ℃. We performed heat treatment with parameters of heat treatment temperature and heat treatment time. By measuring magnetic permeability and microscope images, we found that a heat treatment temperature of 1200 ℃ and heat treatment time of 2 min. is the most appropriate condition. With a he at treatment temperature of 1100 ℃, permeability is not low enough to be considered nonmagnetic.
