Whether it is a structural member or a surface coating, residual stress plays an important role in component performance. When subject to a load, a material responds by straining. Before the yield strength is reached, this strain is reversible as it originates from atomic scale effects. Stress can be frozen in a structure through kinetic limitations, resulting in the material having a residual stress. This can be beneficial if properly engineered, causing the material to resist fatigue, but if too much residual stress is present premature part failure can occur. During this episode of Live from the Lab we will be looking to the analysis of residual stress using conventional and 2D X-ray diffraction.
Broadcast live from Bruker's YouTube channel once each month, our Live from the Lab streaming series explores X-ray Diffraction, X-ray Microscopy, and Elemental Analysis topics, with advice from applications experts who also answer questions that come in during the show.
