【摘要】 本文用高温X射线粉末衍射法研究了成分为(重量百分比)62Fe-23Cr-15Co的可加工永磁合金热处理条件与晶体结构的关系。对高温淬火后只经过时效的样品,以及经过淬火、磁场热处理和时效的样品摄取了高温德拜·谢乐相,观察了高温相变的差异,测量了时效样品点阵常数随温度的变化。我们发现:只经过淬火和时效的样品在610℃左右出现一新的过渡相(X相)。更多还原

【Abstract】 A deformable permanent magnetic alloy, with composition of 62Pe-23Cr-15Co (in wt %), has been studied by high-temperature X-ray diffraction method. Debye-Scher-rer photographs of samples treated with aging in magnetic field and also of those treated without magnetic field were taken. It has been observed that the transformation process with rising temperature up to 800℃ is different in the two classes of samples. The lattice parameters of the samples without a treatment in magnetic field have been measured at various temperatures; and it has been found that in these samples a transitional phase unknown before appeared at 610℃, which was unstable at other temperatures.更多还原
