Until now, shape memory alloys (SMAs) have been largely limited to “remembering” a single memory. In other words, monolithic components only possess a single set of functional properties. The current work describes how theorized change to local chemical composition induced through laser processing enables controlled augmentation of transformation temperatures. Proof of concept was demonstrated by locally embedding multiple shape memories into a monolithic NiTi component. This novel technique overcomes traditional fabrication challenges and promises to enhance SMA functionality and facilitate novel applications through producing a new class of smart materials; namely multiple memory materials (MMMs).
