Systematic differences in beryllium sheet were revealed by an analysis of variance of commercial sheet. A process control and reproducibility study showed that the differences in beryllium sheet are caused by systematic differences between and within hot-pressed billets used for rolling slabs. The rolling process was found to be under control. Causes of variation in tensile elongation were found to be operative within small volumes of single sheet. Breakdown and finish rolling in the temperature range tensile elongation. Reduction ratio was found to have a large effect on the third dimension plastic strain of cross rolled beryllium sheet. Finishing operations such as creep flattening, roller leveling, and roll planishing were investigated, and the effect of these operations on the flatness and tensile properties of beryllium sheet is reported. The effect of various pickling solutions on the bend and tensile properties of beryllium was also studied. (auth)
