Abstract

In this study, the room temperature tensile properties of a single crystal NiAl alloy were investigated as a function of orientation. Fifteen crystallographic orientations were tested, including the <001>, <110> and <111>. The tensile properties measured include yield strength, plastic strain to failure, and ultimate tensile strength. Room temperature ductility as high as 1.4% was measured as close as 10° from the <001> orientation.
