采用高空间分辨率的中子衍射应变测量技术对异种金属焊缝进行了测量。使用三种不同的方法计算并比较残余应力的参考值（d0）。结果强调了由此产生的残余应力分布的d0使用的敏感性，特别是在焊接区域。
Neutron diffraction strain measurements with high spatial resolution were carried out on a dissimilar metal weld (DMW). Residual stress were calculated and compared using three different approaches for reference value (d0). The results underline the sensitivity of the resulting residual stress profiles on the d0used, particularly in the welded region.
