FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, namely to iron-based alloys having high-temperature shape memory effect, and can be used for making high-temperature heat-sensitive elements articles used in aircraft and nuclear industry. Alloy contains 8-13 wt% of nickel, 0.0005-0.0200 wt% of dysprosium, not more than 0.007 wt% of oxygen, rest is iron.
EFFECT: alloy has high ductility, exhibits shape memory effect in range of 658-740 °C, degree of shape recovery of 62-71 %.
