An overview of melting and processing of shape memory alloys is presented by the Consortium for the Advancement of Shape Memory Alloy Research and Technology (CASMART) Processing Working Group. The purpose of this group is to bring together common practices and lessons learned from industry, government, and academia with the objective of establishing guidelines for the production of SMA actuator technology. In this presentation, the various melting techniques are reviewed with a focus on melt size, melt cleanness, and applicability. The effect and importance of composition and the effects of processing on composition are highlighted with examples of commonly produced alloys such as NiTi and NiTiHf formulations. The presentation additionally addresses the need for standards and consistent guidelines to make alloys for applications that require certification. Additionally, recent trends in advanced manufacturing techniques and future directions will be presented.
