In an article by Reid U) dislocation mobilities and energies were evaluated for the b.c.c. refractory metals and iron. The dislocations he considered were edges and screws with various Burgers vectors on the (110) and (100) slip plane. The purpose of this letter is to extend the technique to include the edge dislocation with 4 (111) Burgers vector on the { 112) plane.

limited by some maximum width; that is, the stacking fault energy reaches a minimum value. With regard to the temperature dependence, we must recognize the existence of some temperature above which the binding energy of the solute atoms to the fault is smaller than the energy of thermal motion; thu
We therefore believe that the observed effect is due, not to any magnetostriction of the specimen as a whole, but to the ma~etostrict~ve strain within domain walls. Because the magnetization changes direction within the wall, there must be a change in strain along any line passing through the wall.
If the stresses caused by the particle are such that S, and S, are equal, but different from S,, the third term will drop out, and 8.
