• 論文の詳細を見る

• Magnetostriction has been measured on commercial polycrystalline Fe+27% Co from room temperature to about 600℃, using unbonded strain gages and a high-temperature mounting cement. The gage is excited at 1 kHz, and the sample driven around its hysteresis loop to a maximaum field of about 200 Oe in at time less than 15 seconds to minimize the strain due to temperature drift. Room temperature magnetostriction values agree reasonably well with those quoted by Bozorth (30 to 40 microstrain), and remain almost constan up to at least 350℃, and sometimes higher, depending on the heat treatment of the sample. It therfore seems clear that stress-magnetostriction anisotropy will be significant in these alloys at high temperatures.
