| Abstract Scope |
Neutron scattering is a bulk average non-destructive material characterization of both morphological and crystallographic structures by probing materials and structures under either ex-situ or in-situ/operando conditions by its advances, such as sensitivity to light elements, transition metals, isotopes, nuclear and magnetic structure ordering, as well as deep penetration with complex sample environments, etc. While it is available in national large user facilities, the materials research of high-temperature alloys using neutron on material synthesis, lattice structure, phase transition, physical properties, and deformation mechanisms in extreme environments has become popular and complementary to materials science communities. We show here how new science opportunities in phase evolution and deformation are opened for high-temperature materials communities by the dedicated engineering materials diffractometer VULCAN at the Spallation Neutron Source by its high flux neutrons, wide detector coverage, rapid data acquisition, as well as accommodating large operando devices. |
