Simulation-based matchmaking for shape memory alloys

ScienceDaily (2010-07-06) -- A new shape memory alloy with up to now unprecedented functional stability was developed by researchers in Germany, the U.S., and Japan. Based on a theoretical prediction, they used combinatorial materials science methods -- so-called materials libraries -- for a targeted search of optimized alloy compositions. The result consists of four components: titanium, nickel, copper and palladium. From the new material, the researchers expect a stable shape memory effect and improved lifetime -- for example, in for applications in medical devices such as stents.
