| Abstract Scope |
To accelerate the design of hierarchical/graded microstructures via additive manufacturing, it is essential to identify their complex microstructure-property relationships. These graded materials are often intended for use under varying thermomechanical loading conditions. For example, graded microstructures are being designed to enhance part performance under temperature gradients, with regions optimized for low temperatures and others for high temperatures. We present an accelerated method for evaluating the temperature dependence of microstructure-property relationships by collecting and analyzing large microstructure-correlated datasets of nanometer-scale plastic deformation localization events. These events are captured through high-resolution digital image correlation and mechanical testing under temperature gradients. The evolution of plastic deformation localization from room to high temperatures is examined for several metallic materials, revealing changes in the microstructural effects with increasing temperature due to the transition from slip to grain boundary sliding. Finally, we utilize these plastic localization events to predict the temperature dependence of fatigue properties rapidly. |
