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
