NASA grant funds ‘smart metals’ project
Shape-memory alloys are popular in a range of industries including aerospace and health, and their development was accelerated last month when NASA awarded a $500,000 grant to the A&M team to study their production. These alloys, sometimes called “smart metals,” are lightweight materials that can be deformed and restored to their original shape when heat is applied.
“These are materials that literally have a memory,” said Alaa Elwany, principal investigator of the team. “If it is subjected to some temperature or some abnormal stress then it regains its original shape.”
