Abstract Scope |
High entropy alloys (HEA) attract great attention because of their superior physical and mechanical properties, by compositional optimization. Predictive alloy design through theoretical modeling faces challenges due to the high microstructural and compositional complexity compared to available databases. A large amount of experimental effort is focused on understanding the complex structure-property relationships via conventional characterizations. Neutron scattering is a bulk average non-destructive material characterization of both morphological and crystallographic structures by probing materials with significant advantages e.g. sensitivity to light elements, transition metals, isotopes, nuclear and magnetic structure ordering, as well as deep penetration with complex sample environments, etc. Materials research of HEAs using neutrons for material synthesis, lattice structure, phase transition, physical properties and deformation mechanisms at extreme environments has become popular recently. We show by practical examples that neutron aids the alloy design in understanding material properties, providing predictive model validations and accelerating next generation structural material discoveries. |
