Abstract Scope |
Binary nickel-titanium shape memory alloys (SMAs) developed for wrought manufacturing processes require extensive amounts of cold work to achieve good mechanical performances. Cold working is undesirable in additive manufacturing. To meet this gap, a suite of precipitation hardenable NiTiHf SMAs have been developed for additive manufacturing to span superelastic, actuation, and structural/tribology performances. The metallurgy, thermomechanical properties, applications, and the first laser powder bed fusion process-structure-property relationships of these alloys will be presented. Furthermore, these alloys promise a means for printing multi-functional structures from a single material – the path forward to such technologies will be discussed. |
