Nickel-based superalloy

A high-temperature alloy based on a nickel-rich disordered $\gamma$ matrix, commonly strengthened by ordered ${\gamma }^{\prime }$ precipitates and substitutional solutes.

A turbine blade cast as one crystal to remove high-temperature grain boundary sliding and grain-boundary cavitation pathways. This does not eliminate dislocations or all sources of creep.

The ordered $L{1}_2$ phase based on $\mathrm{N}{\mathrm{i}}_3\mathrm{Al}$ in many nickel-based superalloys. A matrix translation $a⟨110⟩/2$ disrupts its order and can create an antiphase boundary.
