Abstract
Shape-memory alloys (SMAs) have received a great deal of interest due to their excellent properties, which make them significant for various applications. Despite its unique properties, the processing of these alloys is often challenging as it endures a solid-state transition. This chapter thus aims to explore non-conventional machining techniques such as laser beam machining (LBM), electrical discharge machining (EDM) and its associated techniques for the processing of these alloys without altering their intrinsic properties. Both the techniques are discussed in terms of their working mechanism and contribution to the processing of SMA alloys. In addition, the use of EDM processed SMA alloys in various actuators, in particular micromanipulator, micro-positioning stage and tunable coil, is also discussed. Finally, it concludes by discussing the main outcomes of the chapter.
