Hi folks,
A quick question for the guys in aerospace and materials science. A long time ago, I remember hearing about an aircraft alloy (I think it was aluminium based) which followed a hardness curve over about 40 years during normal use (i.e., at normal aircraft operating temperatures). This meant that it was strongest after about 20 years, and then became weaker with age. Can anyone tell me the name of this alloy?
Thanks!
Chris
