How do I increase uniform elongation without losing yield strength in 5754-O?
Thank you, Maui. So far my trials have produced final grain size of ASTM 7.5-8.0. We use TiB2 for grain refinement during casting, but I have not adjusted hot rolling practices beyond "standard" so far. I don't know which direction to go there - aim for a hotter coiling temperature? I've tried...- metals4j

How do I increase uniform elongation without losing yield strength in 5754-O?
No, I'm not purchasing this material, I'm making the material. I work for the mill. I'm trying to create a 1.5 mm AA5754 in the annealed condition with the specified properties (215 MPa TS min, 105 MPa YS min, 19% uniform elongation min) for a customer. I don't have the experience or technical...- metals4j

How do I increase uniform elongation without losing yield strength in 5754-O?
I'm trying to get 1.5 mm AA5754-O sheet to 19% minimum uniform elongation (consistently) while maintaining 105 MPa yield minimum. I can easily get one without the other, of course. I can get both, on occasion, but it's not consistent from sample to sample. At the very best, the yield strength is...- metals4j
