Super alloy Nimonic 80A is the alloy from series NIMONIC nick el-base superalloys that contain 20% ofchromium it is intended for use at elevated and high temperatures at which the creep process occurs significantly. Theprimary strengthening mechanism of this super alloy is based on precipitation of fine and coheren t particle ofintermetallic γ’ phase Ni3 (Al,Ti), which ensure needed creep strength. This strengthening mechanism for such superalloy is more favorable in relation to other strengthening mechanisms. The effect of hardening that can be achieved by γ'phase depends on amount, dispersion, and size of γ' phase. All mentioned is controlled by heat treatment.In the presentwork an attempt has been made to study the effect of two different heat treatment cycles on the microstructures of superalloy Niminic-80A.
