Abstract
Hot-workability tests have been conducted on an Fe-25Ni alloy, which dynamically recrystallizes during testing, to determine the effect of hard oxide inclusions on the ductility. Four different inclusion distributions have been studied and it has been established that for all these distributions ductility increases as strain rate increases and grain size decreases. The volume fraction of oxide is of major importance in determining the hot workability, but for a constant fraction the inclusion size distribution has only a minor effect.
