In one aspect of an inventive concept, a product includes a substrate and a material formed from a precursor powder, where the material includes a plurality of particles from the precursor powder deposited on the substrate. The plurality of particles have structural characteristics defined by an impact of the particles on the substrate and/or on previously deposited particles. Moreover, the material has a microstructure, where the microstructure of the material is substantially the same as a microstructure of the precursor powder. The microstructure of the material is characterized by at least one property, where the at least one property is substantially the same as a corresponding at least one property of the precursor powder.

Cold spray of brittle materials

Production of a bulk Al-RE alloy body (product) using cast billets/ingots (cooling rates <100 C/s) or rapidly solidified Al-RE particulates (cooling rates 10-10° C./second) that have beneficial microstructural refinements that are further refined by subsequent consolidation to produce a consolidated bulk alloy product having excellent mechanical properties over a wide temperature range such as up to and above 230° C.

Thermo-mechanical processing of high-performance Al-RE alloys

A product includes an array of cold spray-formed structures. Each of the structures is characterized by having a defined feature size in at least one dimension of less than 100 microns as measured in a plane of deposition of the structure, at least 90% of a theoretical density of a raw material from which the structure is formed, and essentially the same functional properties as the raw material.

Products and applications for the templated fabrication of materials using cold spray deposition

A product includes a material having: nickel and at least one rare earth element. The at least one rare earth element is present in the material in a weight percentage in a range of about 2% to about 20% relative to a total weight of the material. A method includes forming a material comprising an alloy of nickel and at least one rare earth element. The at least one rare earth element is present in the material in a weight percentage in a range of about 2% to about 20% relative to a total weight of the material.

Castable high temperature nickel-rare earth element alloys

In one embodiment, a magnet includes a plurality of layers, each layer having a microstructure of sintered particles. The particles in at least one of the layers are characterized as having preferentially aligned magnetic orientations in a first direction.

Production of permanent magnets using electrophoretic deposition

An alloy includes aluminum, a rare earth element, and an alloying element selected from the following: Si, Cu, Mg, Fe, Ti, Zn, Zr, Mn, Ni, Sr, B, Ca, and a combination thereof. The aluminum (Al), the rare earth element (RE), and the alloying element are characterized by forming at least one form of an intermetallic compound. An amount of the rare earth element in the alloy is in a range of about 1 wt. % to about 12 wt. %, and an amount of the alloying element in the alloy is greater than an amount of the alloying element present in the intermetallic compound.

Rare Earth Element&#x2014;Aluminum Alloys

In one embodiment, a magnet includes a three-dimensional structure with nanoscale features, where the three-dimensional structure has a near net shape corresponding to a predefined shape.

Samarium cobalt and neodymium iron boride magnets and methods of manufacturing same

A method of making a bulk exchange spring magnet by providing a magnetically soft material, providing a hard magnetic material, and producing a composite of said magnetically soft material and said hard magnetic material to make the bulk exchange spring magnet. The step of producing a composite of magnetically soft material and hard magnetic material is accomplished by electrophoretic deposition of the magnetically soft material and the hard magnetic material to make the bulk exchange spring magnet.
