Advancing the Frontier of High Temperature Shape Memory Alloys

Project for the development of new low-cost, high-temperature SMA alloys that would open doors to numerous applications in the automotive and aerospace sectors.

Unleashing the Potential of High Temperature Shape Memory Alloys

High Temperature Shape Memory Alloys (HT-SMAs) are a cutting-edge class of materials that exhibit remarkable shape memory properties at elevated temperatures. At SAES, we are at the forefront of developing and advancing these innovative alloys for a wide range of applications in the automotive, aerospace, and other industries. Unlike traditional SMAs that operate at lower temperatures, HT-SMAs can withstand extreme thermal conditions, making them ideal for demanding environments where conventional materials would fail.

Innovative Alloys for Extreme Thermal Environments

Binary NiTi alloys have a maximum transformation temperature of As = +95°C. By incorporating various alloying elements such as gold (Au), platinum (Pt), palladium (Pd), hafnium (Hf), and zirconium (Zr), we have successfully achieved significantly higher transformation temperatures for Nitinol-based alloys. This breakthrough allows HT-SMAs to retain their shape memory properties even at temperatures exceeding 600°C, providing unprecedented opportunities for applications requiring exceptional thermal resilience and functional adaptability.

Overcoming Cost and Workability Challenges: Pioneering the Path for High-Temperature SMAs

The development of high-temperature Shape Memory Alloys (HT-SMAs) holds immense promise in the field of material science, offering groundbreaking possibilities across various industries. However, despite their potential, the commercial success of ternary alloys has remained elusive. The high cost of raw materials and the challenges associated with workability at extreme temperatures have been significant hurdles in the development of reliable finished or semi-finished products.

At SAES, we are committed to pushing the boundaries of innovation and exploring uncharted avenues to address these challenges head-on. Our research endeavors focus on the development of new HT-SMAs that not only exhibit exceptional performance at elevated temperatures but also overcome the barriers of cost and workability. By delving into unexplored territories, we strive to create HT-SMAs that are not only cost-effective but also offer enhanced workability, revolutionizing the landscape of high-temperature alloys.
