摘　　要：用X-350A新型X射线衍射仪以等强梁加载法测定了WC硬质合金管螺纹梳刀等强梁的σp-σ'关系。从σp-σ'关系曲线中求出的应力常数和理论计算得出的应力计算值,基本一致。测定结果与日本材料学会测出的相应材料应力常数相接近。According to the equal intensity girder loading method, σp-σ＇relationship curves of WC hard alloy pipe thread tool were obtained by X-350A type X-ray stress diffraction. The stress parameters gotten by above methods coincide basically with the theoretical calculation from σp-σ＇ relationship curves. The stress parameters approaches to the parameters recommended by Japanese material society.
