МАКРОСКОПИЧЕСКИЙ МАГНИТОПЛАСТИЧЕСКИЙ ЭФФЕКТ В КРИСТАЛЛАХ NACL

MACROSCOPIC MAGNETOPLASTIC EFFECT IN NACL CRYSTALS

NaCl crystals were deformed by compression at strain-rates from 10^-5 to 10^-3 s^-1 in a magnetic field 0 - 0,48 T. The stress-strain curves have shown the reducing of the yield point and the total level of the curves as a result of the magnetic field action. The magnetoplastic effect was found to be of the threshold character with two threshold B_c values, the first value corresponding to the origination of the plastifying effect, the second one - to its disappearance.
