Phase-contrast imaging with a hard x-ray grating interferometer is used to increase contrast for weak absorbing materials. It is a well established imaging method to visualize soft tissue in many medical and biological applications. Here we present the approach of using this method in the field of materials science, especially in imaging of new light-weight materials like magnesium and aluminium alloys. We show that more information from a single x-ray projection image can be gained by combining the different contrasts obtained by this imaging method simultaneously. This information can be used to optimize advanced joining techniques for such materials.
