The superplastic behavior of cast and hot-extruded NiAl–28Cr–6Mo is observed in the strain rates between \( \dot \varepsilon \)  = 1.04 × 10−3 and 5.02 × 10−2 s−1 at 1323–1373 K. The synchronous operation of dislocation glide and dynamic recovery is responsible for the tested alloy to exhibit superplastic behavior.
