Since 1932 it has been known that a number of ordered alloys show an unusual kind of deformation behaviour. These alloys (including Au–Cd, Au–Cu–Zn, Cu–Zn–Al, Cu–Al–Ni), after being aged for some time in a martensitic state (the low-symmetry phase of a diffusionless transformation), can be deformed like a soft and pseudo-elastic rubber (with a recoverable strain as large as a few per cent). Accompanying martensite ageing is the development of martensite stabilization (increase in the… CONTINUE READING
