Abstract
The possible smallest twist angle of crack deflection at a boundary between a grain with a typical orientation (such as brass and goss orientations) and a randomly orientated grain was calculated and mapped in Euler space. The orientation of the neighboring grain that showed high resistance to crack growth was identified as a peak in these twist angle plots. The theoretical results were consistent with the results obtained from studies of short crack growth in AA 8090 and AA 2026 Al alloys. The results from this work paved the way to quantification of the texture effects on early growth of fatigue cracks in planar slip alloys.
