Abstract
A method for heat treatment of nonferrous metals and alloys is described which comprises the steps of providing a billet of material comprising nonferrous metal or alloy; rapidly heating the billet to a temperature higher than the transus or solvus temperature of the material whereby a microstructure of uniform single phase grains is formed in a surface layer of preselected depth or other selected region in the billet with the starting microstructure of the material central of the billet; and cooling the billet to room temperature to preserve in the billet surface the high temperature single phase microstructure or a transformation product thereof.
