<p>Embodiments include a method for fabricating a nanograined component from a nanograined powder composition. A compact is formed from the nanograined powder composition and sufficient heat is applied to the compact to generate at least one exothermic reaction while the compact is at a temperature lower than its eutectic temperature. Pressure is applied to the powder compact during the heating operation to consolidate the powder compact. The application of heat and pressure are controlled to inhibit grain growth and form a component having a nanograined microstructure that is at least 98 percent dense at a temperature lower than the eutectic temperature.</p> |
