[QUOTE="Oldhoopster, post: 2769648, member: 84179"]I agree that the area under the Y is sharp, but the other side on the shoulder just doesn’t look like an edge that would come from a lamination. Also, look at the surface of the pit. Lamination surfaces that I’ve seen tend to be more rough and irregular (due to the original surfaces of the gas pockets?). In addition, I think the pit is too deep compared to the length to be a lamination. Remember, that the gas pocket or contamination was originally formed in the cast alloy ingot. As the ingot is rolled, the pocket is elongated along with the metal. I believe the pit is too round and deep have been present when the ingot was rolled into a strip. At least from my standpoint, this has been an interesting discussion. The comments supporting lamination are reasonable, but I think strike through explains the observations better.
