Abstract : The effect of the conditions of preliminary hot rolling (500-1100 degrees centigrade with 20-60 percent reduction) and subsequent cooling (in water, air, or asbestos) on the form of rupture characterizing a number of commercial Ti alloys (VT6S, VT14, VT15, and STI) after subjection to tensile strain was studied. There was a clear correlation between the chemical composition, the rolling conditions, and the form of heat treatment, on the one hand, and the characteristic rupture cross section on the other. After rolling at 1000 degrees centigrade, for example VT15 had a high tendency towards intercrystallite rupture; after rolling at 900 degrees centigrade or under, the fracture had a streaky character.
