Abstract
A method for forming non-equilibrium and/or metastable metallic or non-metallic powder, foil or fine wire material into a solid body comprises charging the material into a metal container, subjecting the metal container containing the material to rolling at a temperature at which the inherent properties of the material are maintained, and thereafter removing the metal container.
Claims7
In a method for forming a non-equilibrium and/or metastable metallic or non-metallic powder, foil or fine wire material into a solid shaped product which comprises charging said material into a metal container of sufficient strength to resist a rolling step;
- heating said metal container containing said powder, foil, or fine wire materials;
- subjecting said container containing said powder, foil, or fine wire material to a forced rolling step whereby a solid shaped product is formed;
- and
- cooling said product;
- the improvement which comprises carrying out said heating by rapidly heating said metal container together with said powder, foil, or fine wire material to a property preserving temperature, and rapidly cooling the obtained solid shaped product.
