Abstract Scope |
In the quest for improved materials, length scale effects are an option for tuning properties. Reduction in grain size can increase strength and manipulation of strut size and distribution in lattice structures can alter myriad properties. A key challenge in using length scale as a tuning parameter is understanding stresses and strains across scales to inform the design process. This talk reviews recent work that leverages a suite of spatially resolved and in situ/operando techniques including diffraction and spectroscopy, to correlate global and local strains and stresses during microstructural evolution. Specifically, linking grain to subgrain scales is addressed. The work presented describes a platform for reliable, multiscale tuning in systems such as additively manufactured materials, high entropy alloys, and fine-grained metals. |
