Work Softening And Annealing Hardening Of Deformed Nanocrystalline Nickel

, 2008
We reported that work softening takes place during room-temperature rolling of nanocrystalline Ni at an equivalent strain of around 0.30. The work softening corresponds to a strain-induced phase transformation from a face-centered cubic (fcc) to a body ...
