X-ray diffraction (XRD) is typically used to measure lattice spacings of a crystalline material for phase identification and quantification. When the crystals are subjected to stress the lattice spacing can increase or decrease, and by measuring these changes using XRD the micro/macro stress-strain state of materials can be evaluated. XRD measurements are non-destructive and requires less rigid sample preparation step making it more suitable for various applications. In this short course the method to evaluate the stress-strain state of a material using diffraction techniques, such as sin2y method, will be introduced along with different case scenarios and examples.
