The National Aerospace Laboratories has initiated research and development on Nickel–Titanium–Hafnium high temperature shape memory alloys. These alloys are designed to exhibit low thermal hysteresis, making them highly suitable for advanced actuation systems operating under elevated temperature conditions.Two alloy compositions have been successfully prepared. The first is Ni50 Ti30 Hf20, and
