The present disclosure is directed to novel high entropy alloys, including refractory high entropy alloys, and methods of selecting high entropy alloys and refractory high entropy alloys with select nuclear application predetermined properties.

High entropy alloys, refractory high entropy alloys, methods of selecting and making, and structures formed thereof

Refractory-reinforced multiphase high entropy alloys (RHEAs) advantageously providing high strength and fracture toughness in an as-AM deposited condition and other conditions are described.

Ultra-high strength multphase high-entropy alloys

The present invention relates to methods of enhancing the surface properties of soft alloys by using a high energy beam. In particular embodiments, the methods can also allow for beam-based welding of such soft alloys to another metal component.

Methods for site-specific enhancement of soft magnetic alloys

Several innovative technologies, including pressure-drop minimization, advanced refractory high entropy alloys, and advanced manufacturing can provide a compact heat exchanger that extends the state-of-the-art heat-exchanger operating range. The compact heat exchanger can reduce pressure drop losses by 100 to 500%, while retaining most of the heat transfer. The compact heat exchanger can be fabricated from refractory high entropy alloys that have favorable corrosion, thermal fatigue, and creep properties at high temperatures and pressures. Therefore, the compact heat exchanger using high entropy alloys can operate at &#x3e;800&#xb0; C. and 80 bars.

Processes for producing continuous bulk forms of iron-silicon alloys and bulk forms produced thereby. Such a bulk form is continuous in a longitudinal direction thereof and has a continuous cross-sectional form transverse to the longitudinal direction. The bulk form is formed of an Fe&#x2014;Si alloy and has a crystallographic texture that comprises &#x3c;111&#x3e; and {110} fibers that are inclined relative to the longitudinal direction. The bulk form may be produced by a process that includes deforming a solid body formed of an Fe&#x2014;Si alloy with a cutting tool in a single step to continuously produce a continuous bulk form from material obtained from the solid body.
