Memory alloys that avoid exhaustion Shape memory alloys can pop back into shape after being deformed. However, often these alloys cannot cope with a large number of deformation cycles. Chluba et al. find an alloy that avoids this pitfall, deforming 10 million times with very little fatigue (see the Perspective by James). Such low-fatigue materials could be useful in a plethora of future applications ranging from refrigerators to artificial heart valves. Science, this issue p. 1004; see also p…
