The Functional Materials Lab is committed to the development of a distinctive category of metallic functional materials known as shape memory alloys (SMAs). Our research is centered on the exploration of TiNi-based, CuAl-based, and high-entropy SMAs to enhance their shape memory capabilities and stability. In pursuit of these objectives, we employ approaches such as alloy design, heat treatment, and control of microstructures. Our investigations involve the extensive application of material characterization techniques, encompassing thermal analyses, microstructural observations, temperature-dependent measurements of mechanical properties, and non-contact measurement methods, to unveil the underlying mechanisms of novel results.

If you share an interest in these topics, we extend a warm invitation for you to join us!

🎉News & Awards 🏆

• 2025.8 🎓 Congratulations to Ji-Kuang Jiang (江繼光), whose master's thesis has been honored with the Dean's Award for outstanding graduate research in the College of Engineering.

• 2025.8 Our latest publication in Materials Today Advances explores how crystal orientation and operating temperature influence the superelasticity and elastocaloric effect of CuAlMn-based SMAs.!

• 2025.1 In our latest work, we collaborated with Prof. 貝沼亮介(Ryosuke Kainuma) from Tohoku University, which has been published in Scripta Materialia. This study utilized the rapid solidification process of melt-spinning to prepare a high-entropy shape memory ribbon, (TiZrHf)50Ni35Co10Cu15, with enhanced ductility.

• 2024.8 Our latest article on a (Ni,Cu)-rich TiNiCu shape memory wire has been published in the Journal of Alloys and Compounds. We demonstrated a method to fabricate TiNiCu wire that exhibits stable superelasticity and elastocaloric effect.

• 2024.5 Our latest research on functionally stable TiNiCu shape memory alloy has been published in the Journal of Alloys and Compounds.
