Morphology and texture evolution of FeCrAlTi–Y2O3 foil fabricated by EBPVD
چکیده انگلیسی

An electron beam physical vapor deposition method was used to fabricate freestanding Y2O3 dispersive strengthened FeCrAlTi foils for high-temperature applications. The vapor incidence mode was found to have great impact on the morphology and crystallographic orientation of the foils. Under symmetric vapor incidence mode, an out-of-plane < 100> fiber texture was formed. While under asymmetric vapor incidence mode, both out-of-plane preference of < 111> direction and several in-plane preferences were developed. As the deposition proceeded, the extent of in-plane orientation increased, and the preferred out-of-plane orientation increasingly deviated from the surface normal. The vapor incidence mode played a role on the growth rate of < 100> direction and < 110> direction, by which the morphology and crystallographic orientation of grains were modified.
