摘要	Polycrystalline Ni with a purity of 99.7% (with 0.14% Ti) has been deformed by high-pressure torsion at room temperature to epsilon(upsilon M) = 100. The presence of solute atoms markedly raises both the strength and the thermal stability, showing a flow stress of about 1700 MPa and a recrystallization temperature of about 500 degrees C. The effect of the solute on dislocation storage during deformation and on the mobility of dislocations and boundaries during annealing are discussed. The strengthening mechanisms and their super-position are also analyzed. (C) 2011 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
