1.Microalloying of ZhS6K with 0.01–0.8% Y leads to formation of yttrium oxide Y2O3, which precipitates in the form of "chains" and "placers", and of intermetallic Ni3Y localized both within grains and along their boundaries, and leads to a reduction in coalescence rate for ?'-phase particles and retardation of the process of M6C carbide formation of acicular form during aging.2.Structural changes in the alloy, caused by introducing small amounts of yttrium, lead to a reduction by a factor of 1.5–2 in the short-term ductility and impact strength. |
