| Abstract Scope |
Construction of spatial heterogeneity guide maps provide effective guidance regarding mechanical behavior of additively manufactured materials. High resolution measurements of micromechanical properties become an integral part of the studies in additive manufacturing since the mechanical behavior of the individual nano scale phases are responsible for determining the overall mechanical response of the material. Thus, the characterization and quantification of these constituent phases hold the answer to the overall property improvement, calibration, and quality certification of any additively manufactured alloy. In this research a high throughput nanoindentation method for such measurements has been proposed at multiple scales which can be extrapolated to deduce the overall mechanical behavior of additively manufactured alloys. Various aspects and characteristics of the nanoindentation curves are carefully interpreted to extract information about the micromechanical response at various length scale. |
