A method for increasing the strength of metals or metal components includes selecting a wrought metal or powder metal sample having a mass equal to or greater than a final mass of a component to be formed. If the sample is wrought metal, it is placed in a die cavity and subjected to high velocity adiabatic impact that forms a component having greater mechanical strength than the original wrought metal sample. If the sample is powder metal, it is placed in a die cavity and subjected to high velocity adiabatic impact to form a green preform that is sintered in a substantially oxygen free environment to form a sintered preform. The sintered preform has greater mechanical strength than a conventional wrought metal sample of the same material. The sintered preform may be optionally placed in a final die cavity and subjected to high velocity adiabatic impact to form a component. |
