Effect of a heterogeneous distribution of particles on the formation of banded grain structure in wrought Alloy 718 [PDF]
, 2005 Alloy 718 is known to be sensitive to interdendritic segregation formed during ingot solidification. The occurrence of banded grain structures under heat treating conditions close to 1000 ° C related to interdendritic segregation is often reported.

A Novel Approach for ∆K Estimation in the Fatigue Threshold Region Based on ΔKth and Kmax,th
Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 2, Page 653-662, February 2026.ABSTRACT A novel procedure, proposed by Kujawski and Vasudevan 1, has been evaluated as an alternative to the ASTM E647 standard for determining the ∆Kth and Kmax,th thresholds. This method relies solely on the actual propagation of cracks, which occurs only when both thresholds are satisfied simultaneously. For long cracks, a more efficient estimation
