Nanocrystalline shape memory alloys lose their memory as the crystalline grains get smaller
The ability of shape memory alloys, used as materials for medical stents, to revert to their original shape after an increase in temperature is suppressed at nanometer grain sizes due to effects related to the larger proportion ...
