| Abstract Scope |
Functionally graded alloys have shown their ability to locally optimize properties, such as in components where one region requires a higher elastic modulus than another region. Most studies have been performed in the context of linear gradient transitions, leaving the property changes and interactions within a compositional, ternary, 2D gradient space relatively unexplored. By spatially controlling elemental Cr, Fe, Ni powder compositions, samples were manufactured via Spark Plasma Sintering (SPS) to provide a comprehensive understanding of the gradient properties across the entire Cr-Fe-Ni ternary space. Heat treatments were performed to further homogenize the sample, smoothing the gradient transitions. Characterization was performed both after SPS and after heat treatments in order to map the compositional, microstructural, hardness, moduli, and magnetic properties. Following characterization of this material space, analyses were performed to verify Cr-Fe-Ni laser additive manufacturing feasibility maps. |
