| Abstract Scope |
Despite the finite number of usable elements, there are still elements that can be alloyed with iron which are still poorly understood. Strontium one of those elements. In this work, we study the FeSr system and its potential as a surprisingly promising and economical Rare Earth ODS alloy with promising ability to form hierarchical microstructures through time and temperature control. Experimental work first yields surprisingly rich multiscale behavior and promising properties for this ill-explored system. To better understand the behavior we observe in this system, a complex mesoscale microstructure model has been developed to simulate the salient features, which include concurrent anisotropic grain growth, phase change, and particle pinning, among other things. Due to the complexity of the system, the differences between microstructures are studied through the lens of modern machine learning approaches. |
