Properties of a 45Ti–45Ni–10Nb shape memory alloy in the as-cast and pressed states
Abstract
The structural and functional properties of specimens cut from as-cast and pressed rods of a 45Ti–45Ni–10Nb (at %) alloy have been studied in as-delivered state. The homogeneity of the properties under study has been verified along the rod length and from rod to rod. The laws of formation of the alloy structure as a function of the technology of its manufacturing have been studied. The structure influences the mechanical behavior and the main functional properties of the alloy. The pressed state is shown to be preferable as compared to the as-cast state.
