摘要:

Quantitative pole density stereograms of {111}, {220}, {200}, and {113} poles of ⅛‐mil molybdenum permalloy tape were developed in order to establish its cold rolled deformation texture and annealed textures.Cold rolled the tape induced multiple slip common to all face‐centered‐cubic metals and developed (110) [3¯35] and (110) [33¯5] end orientations which deviate 5° about [110] from the recognized {110} ⟨112⟩ brass deformation texture.On annealing at 771°C the cold rolled tape was found to develop (120) [001]+(210) [001] and (113) [7¯8¯5] +(113) [785¯] orientations as components of the annealed texture which bear in general at 35°‐45° rotation orientation relationship about ⟨111⟩ with the cold rolled end orientations.Annealing at 1160°C developed the same texture as that obtained after 771°C annealing.From the pole figures made on 927°C annealed tape, the same annealed texture prevailed whether the pole figure was made on its full ⅛ mil thickness or on its central 0.00005 in. section.Hysteresis loop tracings made on the cold rolled tape revealed an apparent direction of easy magnetization along the rolling direction. No easy magnetization direction was revealed in the rolling plane on the annealed tapes. These findings support the deductions from the corresponding pole figures.
