| Abstract: | The effect of stablilization treatment on microstructures and stress- rupture properties of GH738alloy bars is investigated.It is shown that the stabilization treatment signifi- cantly increases the stress- rupture life of smooth specimens and notched specimens,elongation, and avoids the notch sensitivity of the alloy. |

| Keywords: | superalloy stress- rupture properties notch sensitivity |
