METHOD OF MAKING RHENIUM COATING
A method of forming rhenium coated metal particles includes directly mixing ammonium perrhenate with metal particles and converting the ammonium perrhenate to a rhenium coating on the metal particles. Other methods include forming rhenium coated cubic boron nitride particles and rhenium coated diamond particles. Components of tools may be manufactured using the rhenium coated metal particles, the rhenium coated cubic boron nitride particles and/or rhenium coated diamond particles.
ALUMINUM ALLOY POWDER FORMULATIONS WITH SILICON ADDITIONS FOR MECHANICAL PROPERTY IMPROVEMENTS
An improved aluminum alloy powder metal includes silicon additions. When this improved powder metal with silicon additions is sintered to form a sintered component, the resultant component exhibits many improved mechanical strength properties and improved thermal resistance.
THREE-DIMENSIONAL PRINTING
An example of a three-dimensionally printed object includes a bulk portion having a ferritic microstructure; and a site-specific alloyed section having a pearlite microstructure. The three-dimensionally printed object may be generated using different examples of a three-dimensional (3D) printing method. Each example of the 3D printing method utilizes a two-stage heat treatment.
Multi-material structures and methods
A multi-material structure includes a refractory portion with a metal or metal alloy of at least one of niobium (Nb), molybdenum (Mo), tantalum (Ta), tungsten (W), rhenium (Re), iridium (Ir), vanadium (V), and ruthenium (Ru). A structural portion is metallurgically joined with the refractory portion. The structural portion includes a titanium (Ti) alloy. At least one of the refractory and structural portions is additively manufactured.
Tungsten carbide-based cemented hard material
A tungsten-carbide-based hard material includes the following components: tungsten carbide with an average particle size of 0.1-1.3 m; 1.0-5.0 wt. % (Co+Ni), with a ratio of Co/(Co+Ni) in wt. % of 0.4Co/(Co+Ni)0.95; 0.1-1.0 wt. % Cr, with a ratio of Cr to (Co+Ni) in wt. % of 0.05 Cr/(Co+Ni) 0.20; 0.01-0.3 wt. % Mo; and 0.02-0.45 wt. % Me, where Me represents one or more elements from the group Ta, Nb, Hf and Ti, preferably Ta and/or Nb; and wherein 0.01Me/(Co+Ni)0.13.
