Abstract

Disclosed are computer systems for and methods of identifying non-elemental materials based on atomistic properties. The computer systems and methods may permit the identification of non-elemental materials having one or more desired material properties which may be specified in the form of user input. The materials identified may be known or predicted by the computer systems and the methods to exhibit the desired material properties.

Abstract

Metallic matrix composites include a high strength titanium aluminide alloy matrix and an in situ formed aluminum oxide reinforcement. The atomic percentage of aluminum in the titanium aluminide alloy matrix can vary from 40% to 48%. Included are methods of making the metallic matrix composites, in particular, through the performance of an exothermic chemical reaction. The metallic matrix composites can exhibit low porosity.

Abstract

Articles are manufactured using self-propagating high-temperature synthesis (SHS) reactions. Particulates including reactants can be blended to form a particulate blend. The particulate blend can be preformed. The preform article can be heated to a pre-heat temperature being below an auto-activation temperature and above a minimum compression activated synthesis temperature. Compressive stress can be exerted on the preform article at the pre-heat temperature to initiate the SHS reaction between the reactants and thereby form a product metallic compound. At approximately peak temperature, a flow stress of the product metallic compound can be exceeded to substantially reduce porosity and thereby form a shaped substantially dense article.

Abstract

Metallic matrix composites are synthesized by mixing a first reactant, a second reactant and a nucleator compound to obtain a reaction mixture, and heating the reaction mixture to an auto-activation temperature to initiate a self- propagating high-temperature synthesis reaction between the first and second reactants. The metallic matrix composite can include a metallic matrix and an in situ formed reinforcement. The reinforcement can be formed of discrete particles substantially uniformly dispersed within the metallic matrix. Each of the particles can have a reinforcement constituent disposed about a core formed of the nucleator compound.
