研究结果得出：Inconel718合金经1040℃固溶处理720℃8h，55℃／h炉冷，620℃8h时效后，存在缺口敏感性。该合金经970℃固溶处理和时效后没有缺口敏感性，并且屈服强度和抗拉强度随冷轧变形量的增加而提高。在1040℃＋850℃（中间处理）并时效后，可以消除缺口敏感性，但合金强度随之显著降低。
The results show that the Inconel718 alloy has a notch sensitivity after being solution treated at 1040 ℃ for 8h at 720 ℃, furnace cooling at 55 ℃ / h and aging at 620 ℃ for 8h. The alloy has no notch sensitivity after solution treatment and aging at 970 ℃, and the yield strength and tensile strength increase with the increase of cold rolling deformation. Gap sensitivity can be eliminated at 1040 ° C + 850 ° C (intermediate treatment) and aged, but the alloy strength is significantly reduced.
