摘　　要：介绍了一种采用X-射线衍射仪精确测量具有织构的钢铁材料中奥氏体含量的方法。本方法的特点是将试样中的衍射峰分成两组,分别采用不同波长的辐射源测量每组中各衍射峰的面积并计算出材料中残余奥氏体含量。该方法可有效减少因织构带来的测量误差。A method to determinate retained austenite in steels with preferred orientation using an X-ray goniometer was introduced~ The method is characteristics of dividing diffraction peak of the sample into two groups. Radiation source with different wavelengths is adopted to measure the diffraction peak area respectively and calculate the retained austenite content in the material. The method can effectively reduce the measurement error brought by the texture.
