摘要：
The influence of applied tensile stresses (16-45 MPa) during Joule-heating thermal treatments on samples of nominal composition Co66Fe4Mo2Si16B12 is reported. The influence of high axial stresses (0-1000 MPa, applied during measurements) on the coercive field was also investigated. The coercive field exhibited a maximum as a function of measuring stress. Very low values of the saturation magnetostriction constant have been obtained as a function of annealing stress.
