Effect of annealing on magnetostrictive characteristics of a grain-oriented electrical steel with ordinary and refined domain structure

摘要: We present the results of investigating effect annealing on magnetostrictive characteristics a grain-oriented electrical steel (GOES) with ordinary and refined domain structure. Not infrequently, sheet samples leads to an increase in electromagnetic induction B 100 and, simultaneously, enhancement specific losses P 1.7/50. In GOES structure, minimum absolute values λ0-peak λpeak-peak are observed before annealing. For these samples, after annealing, impaired most severely. The mechanism for explaining this experimental fact has been suggested.
