Microhardness and microstructural evolution in pure nickel during high-pressure torsion
Microhardness and microstructural evolution in pure nickel during high-pressure torsion
The microhardness and microstructural evolution during high pressure torsion testing in samples of pure nickel were investigated. Results were obtained on Ni samples subjected to annealing prior to high pressure torsion. A detailed TEM and X ray study were used. During torsion, the final microstructure was independent of the grain size. It was demonstrated that the processing parameters of strain and applied pressure were important for microhardness refinement and increased microhardness during high pressure torsion.

Abstract
The microhardness and microstructural evolution during high pressure torsion testing in samples of pure nickel were investigated. Results were obtained on Ni samples subjected to annealing prior to high pressure torsion. A detailed TEM and X ray study were used. During torsion, the final microstructure was independent of the grain size. It was demonstrated that the processing parameters of strain and applied pressure were important for microhardness refinement and increased microhardness during high pressure torsion.
