摘要

研究了稳定化处理对GH738合金棒材微观组织和持久性能的影响,证明稳定化处理可大幅度提高合金棒材的光滑持久寿命、延伸率和缺口持久寿命,避免缺口敏感性。

Abstract

The effect of stablilization treatment on microstructures and stress-rupture properties of GH738 alloy bars is investigated.It is shown that the stabilization treatment significantly increases the stress-rupture life of smooth specimens and notched specimens,elongation, and avoids the notch sensitivity of the alloy.
