Nickel Titanium Alloys, Methods of Manufacture Thereof and Article Comprising the Same

[摘要] Disclosed herein is a shape memory alloy comprising 48 to 50 atomic percent nickel, 15 to 30 atomic percent hathium, 1 to 5 atomic percent aluminum; with the remainder being titanium. Disclosed herein too is a method of manufacturing a shape memory alloy comprising mixing together to form an alloy nickel, hafnium, aluminum and titanium in amounts of 48 to 50 atomic percent nickel, 15 to 30 atomic percent hafnium, 1 to 5 atomic percent aluminum; with the remainder being titanium; solution treating the alloy at a temperature of 700 to 1300.degree. C. for 50 to 200 hours; and aging the alloy at a temperature of 400 to 800.degree. C. for a time period of 50 to 200 hours to form a shape memory alloy.
