An alloy is a substance composed of two or more chemical elements, at least one of which is a metal, forming a single or multiphase metallic material with modified physical, chemical, and mechanical properties relative to its constituent elements. At the atomic scale, alloys may exhibit substitutional or interstitial solid solutions, ordered phases, or complex microstructures generated by phase transformations and thermal or mechanical processing. Alloy design and characterization focus on composition, phase equilibria, microstructural features (such as grains, precipitates, and defects), and resulting properties including hardness, strength, ductility, corrosion resistance, electrical conductivity, and thermal stability, which are tailored for specific technological and industrial applications.
Caltech scientists have developed a method to create metallic objects of a precisely specified shape and composition, giving them unprecedented control of the metallic mixtures, or alloys, they create and the enhanced properties ...
