Abstract
The P effect on the superplastic deformation of NiAl has been investigated. It is shown that P segregates to grain boundaries and the segregation has profound influence on the high temperature tensile properties of the NiAl alloy. The segregation retards dynamic recovery and recrystallization that leads to a decrease in elongation and enhancement in cavitation compared with the stoichiometric NiAl. Therefore, the P has harmful effect on the superplastic deformation of NiAl.
