As can be seen from Fig. 2 the magnetostrictive sensitivity of nickel is rising almost monotonically with an increase of annealing temperature. The local maximum is found at temperatures close to the Ni recrystallization temperatures. 4. Conclusion It is shown that the coercive force decreases monotonically by a factor of 25 with an increase in the annealing temperature of cold- worked nickel from 100 to 900°C. It has been established that the magnetostrictive sensitivity dλ/dH of cold -worked and annealed nickel increases by more than 3 times with an increase in the annealing temperature. The observed changes in the magnetic properties are due to recrystallization processes.
