Abstract : The transverse bend transition temperatures of a molybdenum alloy with carbon levels of 0.03, 0.07, and 0.10% are shown to be within the limits of -100 to +250 F. The sheet rolled directly from sheet bar to finished gage without intervening anneal generally possesses the lowest transition temperature. Differences in transition temperature between the cold worked and recrystallized structures are generally small. Laminating tendency is shown to be associated with the cold worked structure. With the advance of recrystallization it disappears. A condition of about 30% recrystallization corresponds to the disappearance of laminating tendency and a maximum in bend-rebend ductility.
