The proposed research program will act as a platform for the long-term vision of bridging the gap between industrial design/application and material science, furthering shape memory alloy (SMA) technologies to the point where industry can reap their full potential. More specifically, the proposed next term of discovery research will focus on furthering extremely promising laser processing technologies, addressing past issues identified in literature and building on fundamental discoveries from the applicant's previous discovery program. The key objectives of this research are: i) understand and develop quantitative relationship between phase transformation temperatures and laser processing conditions; ii) Investigate the effects of laser processing conditions on the shape memory effect and pseudoelastic properties; iii) understand and improve upon the corrosion performance and biocompatibility of processed material; and, iv) disseminate core research to facilitate the development of new applications where laser technologies can benefit industry and fundamental SMA research.

拟议的研究计划将作为弥合工业设计/应用与材料科学之间差距的长期愿景的平台，推动形状记忆合金(SMA)技术的发展，使工业能够充分发挥其潜力。更具体地说，拟议的下一期发现研究将侧重于进一步发展极具前景的激光加工技术，解决过去文献中确定的问题，并建立在申请者先前发现计划的基础上。这项研究的主要目标是：i)了解和发展相变温度和激光加工条件之间的定量关系；ii)调查激光加工条件对形状记忆效应和伪弹性性能的影响；iii)了解和改善加工材料的腐蚀性能和生物相容性；以及，iv)传播核心研究，以促进激光技术可以有益于工业和基础SMA研究的新应用的开发。
