Cryo-rolling of Cu Alloys: Part One

Cryo-rolling is effectively deformation of materials at liquid nitrogen temperature (LNT) that assists in producing ultra-fine grained microstructures.
Resulting gains can be made in the mechanical properties of the material and in studied cases, it was found that with a 40% thickness reduction through conventional and cryo-rolling techniques and improvement in hardness can be made from 85HRB to 90.8HRB respectively. Continue reading
