High-throughput diffusion multiples

摘要: A diffusion multiple is an assembly of three or more different metal blocks, in intimate interfacial contact, subjected to high temperature allow thermal interdiffusion create solid-solution compositions and intermetallic compounds. Using microscale probes, composition-structure-phase-property relationships can be established with efficiency orders magnitude higher than conventional one-composition-at-a-time practice. For structural materials, such include phase diagrams, coefficients, precipitation kinetics, solution strengthening effects, effects. Many probes also used study several materials phenomena. instance, conductivity measurements order-disordering transformation, site preference compounds, effect on conductivity, compositional point defect propensity. This article will use a few examples illustrate the capabilities developmental needs this approach.
