An assessment of a microsegregation and allocations of secondary phases at electron beam additive formation of a product from a nickel alloy

The group of employees of LLMAT, LFUP and LKKMIK conducted research of chemical and phase composition of a product from a heat resisting nickel alloy of ZhS6U created by wire electron beam Additive technologies. The microsegregation assessment on macro - (dendrites / mezhdendritnoye space) and microscale (γ/γ ˈ) is carried out. Modern alloys on the basis of nickel are slozhnolegirovanny and may contain about 10 entered chemical elements. Despite that each element is entered with a definite purpose (stabilization and hardening γ phases, education γ ˈ a phase and carbides, resistance...
