Преимущественная ориентация и дефектное строение γ΄- фазы в сплаве на основе Ni-Al-Cr, легированного лантаном

Abstract

Methods of the diffraction submicroscopy on thin folga conducted a research of slozhnolegirovanny superalloy on the basis of Ni-Al-Sr prepared with method of a directional crystallization containing, by γ′-and γ phase. It is established that introduction to alloy of a lanthanum changes preferred orientation of γ′ - phase. Annealing of the alloy alloyed by a lanthanum leads to scattering of texture.
