A method for manufacturing a dense consolidated volume of a nanostructured material is provided. The method includes providing a plurality of portions formed from a high strain deformation process and having a nano-sized grain structure therein. One surface of each portion may then be contacted against a surface of another portion. Thereafter, ultrasonic vibrations may be applied along at least one of the portions to permit the contacting surfaces to bond with one another without substantially melting the portions, so as to form a consolidated volume. A bulk ultrasonically consolidated nanostructured material or mass is also provided.
