Thanks unclesyd and kenvlach,
I was reducing the strip of al-cu for a shimming application. I decided to hot roll in an effoet to reduce forces. I did consult the phase diagram and was advised to stay below the liquidus line.I dont have the series number for the alloy.Will i try 350-375 f?
I needed to reduce the thickness of a strip of al- 3%cu. I heated it to 575 degree c but it fragmented and broke into pieces on rolling. Any one know why? Should i have annealed it?
