Desirable work hardening for plasticity of metal

Dear all,

As we know, the work hardening of metallic materials is a result of dislocation movement within the material. But, is there a case in which work hardening is desirable to enhance the plasticity of the metal material? If yes, what's the relationship between plastic deformation and work hardening? Thanks in advance!

Best regards,
Damien

I'm not a metallurgist, but speaking from practical experience, I have never found a metal that becomes more plastic after work-hardening (or post hardening of any type). It actually sounds impossible, to me.

From the many alloys I used, none would get more plastic.
But there are so many alloys, with such exotic properties!
