Abstract: A system and a method for fabrication of bulk nanocrystal alloys are provided. The method includes subjecting powders of at least one material to an ultrasonic vibration at a first amplitude, heating the powders in response to the ultrasonic vibration at a first temperature elevating rate corresponding to the first amplitude, and treating the powders in a temperature range corresponding to the first temperature elevating rate, obtaining a bulk material composed of a plurality of crystal grains. The method may further include obtaining a bulk material with amorphous structure with sufficient temperature cooling rate.
