Superplastic behavior of an extruded eutectic NiAl/Cr(Mo) alloy at intermediate strain rate region

The superplastic behavior of cast and hot-extruded NiAl–28Cr–6Mo is observed in the strain rates between _ e = 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.
