Claims27
A nanostructured titanium alloy article, comprising:
- a developed titanium structure having ≧80% of grains being of a size ≦1.0 micron.
A method for making a nanostructured titanium alloy, comprising the steps of:
- providing a workpiece of a titanium alloy;
- inducing severe plastic deformation to the workpiece using an equal-channel angular pressing-conform machine at temperatures ≦650° C. and having a die set at a channel angle of intersection between ψ=75° and ψ=135°;
- and
- subjecting the workpiece to thermomechanical processing at temperatures ≦550° C. to prepare an article having a cross-sectional area reduction ≧35%.
