Abstract : Progress is reported on a preliminary rolling study to determine the effects of rolling temperature and reduction on rollability and properties of W sheets. Preliminary work on InFab processing is discussed. From a rollability standpoint (i.e., material rolls satisfactorily without breaking up), initial rolling temperatures as low as 2300 F are satisfactory. Final rolling temperatures as low as 1800 F also proved satisfactory. The following ranges of processing parameters resulted in the lowest bend transition temperatures: (1) initial rolling at 2300 to 2500 F as compared to 2700 F, (2) reductions greater than 90% after recrystallization as compared to 80, 60, and 40%, and (3) maximum annealing temperature of 2000 F attributed to the initiation of recrystallization. Specimens were bent at 275 F which was the lowest temperature investigated. InFab forging of extrusions at 3000 to 4000 F proved satisfactory from a workability standpoint. (Author)
