Feasibility of selectively enhancing the surface properties without sacrificing the bulk strength properties of agehardenable alloys is demonstrated by generation of local surface plastic deformation by indentation. The results indicate that the current strategy of local surface deformation can be extended other precipitation hardenable alloys to tailor the properties as desired. © 2006 Elsevier Ltd.

Influence of cryo-rolling reduction and annealing of commercially pure (CP) Al is evaluated in four aspects: microstructure, mechanical properties, electrical conductivity and general corrosion. It is shown that by selecting optimal cryo-rolling reduction and subsequent annealing condition result in ultrafine grains in CP Al with good combination of high strength and ductility. Electrical conductivity of the cryo-rolled samples decreased due to increased number of the electron scattering centers (lattice defects and grain boundary area). However, optimization of cryo-rolling and annealing treatment could restore the conductivity coupled with high strength in CP Al. Corrosion behaviour of cryo-rolled CP Al improved after annealing treatment. High dissolution rate and low thermal stability of the ultrafine grain structure could override the anticipated advantage of uniform corrosion in ultrafine grain CP Al. © 2005 Elsevier B.V.
