中文摘要：

剩余应力是为评估设计材料的变丑和失败的一个重要因素。基于衍射的测量假设完整的测量格子紧张张肌根据胡凯斯·劳的意见贡献剩余应力。格子的现在的工作焦点借助于微分孔的 X 光检查在双阶段的不锈钢(DPSS ) 拉紧单个谷物的决心微衍射(DAXM ) 。结果证明剩余压力仅仅全部的测量格子紧张的责任参加。事实上，在材料内的组合变化被发现在铁酸盐引起更大的紧张坡度() 并且奥氏体() 在 DPSS 的阶段。因此， quantification 组合并且格子紧张上的剩余压力效果被进行以便在设计材料内评估真剩余压力。

英文摘要：

Residual stress is an important factor for evaluating the deformation and failure of engineering materials. Diffraction-based measurement assumes that the full measured lattice strain tensor contributes to residual stress according to Hookers Law. The present work focuses on the lattice strain determination of individual grains in a dual-phase stainless steel （DPSS） by means of differential-aperture X-ray micro-diffraction （DAXM）. The results show that the residual stress only takes part of the responsibility of the total measured lattice strain. In fact, the compositional variation inside the material was found to cause greater strain gradient in both ferrite （c~） and austenite （~） phases in DPSS. Therefore, quantification of compositional and residual stress effects on lattice strain was conducted in order to evaluate the true residual stress inside engineering materials.
