"A superelastic alloy with a nearly limitless temperature window"

A team of researchers at Tohoku University has developed a new kind of superelastic alloy with a nearly limitless superelastic window....snip

....During testing, its superelastic window was found to be 10 to 473 K (-263 C° to 200 C°), making it applicable in virtually all natural settings. The researchers note that the alloy was also found to have very low thermal expansion.

The team created the alloy by adding chromium to a Fe-Mn-Al-Ni alloy. In so doing, they also showed that entropy change is controllable using this approach. The entropy change for the new alloy was tested to be very near zero. The researchers also note that the alloy is tunable by varying the amount of chromium, which highlights the fact that the team actually created a host of superelastic "invar" alloys."
