Abstract
Methods of imparting ultra-fine grained (UFG) structure to conventiona l aluminium alloys by thermomechanical treatment, including severe pla stic deformation, are analysed. The effect of initial structure parame ters, such as grain size and precipitates of secondary phases, on UFG structure formation is discussed in terms of physical mechanisms. Ambi ent temperature mechanical behavior of UFG alloys produced by several methods is reported. The effect of grain refinement on static strength and toughness is more pronounced in non-heat treatable alloys. Evolut ion of UFG structure during post-deformation heat treatment and superp lastic behavior of UFG alloys is shown. (C) 1997 Elsevier Science S.A.
