I want to roll or convert bismuth pieces into thin sheets of bismuth. Is there any way by which i can do that as bismuth is relatively brittle and breaks easily while rolling in a rolling mill or when hammered to decrease thickness.

One can try with hot rolling. Another way is to cold rollling with very very small deformation in each step (needs trial and error) followed by intermediate recrystallizing heating for short time.

A cycle of heat and cold rolling can work but you have to be optimize it for the timings of hot and cold rollings.
