Patent number: 11969797Abstract: A syntactic metal foam composite that is substantially fully dense except for syntactic porosity is formed from a mixture of ceramic microballoons and matrix forming metal. The ceramic microballoons have a uniaxial crush strength and a much higher omniaxial crush strength. The mixture is continuously constrained while it is consolidated. The constraining force is less than the omniaxial crush strength. The substantially fully dense syntactic metal foam composite is then constrained and deformation worked at a substantially constant volume. The deformation working is typically performed at a yield strength that is adjusted by way of selecting a working temperature at which the yield strength is approximately less than the omniaxial crush strength of the included ceramic microballoons. This deformation causes at least work hardening and grain refinement in the matrix metal.Type: GrantFiled: October 28, 2021Date of Patent: April 30, 2024Assignee: Powdermet, Inc.Inventors: Andrew Sherman, Brian Doud

Patent number: 11572508Abstract: A non-linear surfactant, and particularly a non-linear surfactant comprising bi-functionalized molecules or particles having both hydrophobic and hydrophilic groups. The non-linear surfactant includes a nanoparticle template of a rigid molecular structure, wherein the nanoparticle comprises a molecule or a particle that is bi-functionalized with both hydrophilic and hydrophobic groups to obtain an amphiphilic nanoparticle. The template nanoparticle can be used as a surfactant, wetting agent, emulsifier, detergent or other surface active agents or for the preparation of nanoemulsions or dispersions. The non-linear surfactant can provide smaller particle sizes for emulsion suspensions and foams.Type: GrantFiled: April 22, 2021Date of Patent: February 7, 2023Assignee: POWDERMET, INC.Inventors: Andrew Sherman, Brian Werry

Patent number: 11534845Abstract: A heterogeneous composite consisting of near-nano ceramic clusters dispersed within a ductile matrix. The composite is formed through the high temperature compaction of a starting powder consisting of a core of ceramic nanoparticles held together with metallic binder. This core is clad with a ductile metal such that when the final powder is consolidated, the ductile metal forms a tough, near-zero contiguity matrix. The material is consolidated using any means that will maintain its heterogeneous structure.Type: GrantFiled: July 8, 2021Date of Patent: December 27, 2022Assignee: POWDERMET, INC.Inventors: Mark Grogan, Brian Doud, Andrew Sherman

Patent number: 11530170Abstract: A high strength engineered reactive matrix composite that includes a core material and a reactive binder matrix combined in high volumes and with controlled spacing and distribution to produce both high strength and controlled reactivity. The engineered reactive matrix composite includes a repeating metal, ceramic, or composite particle core material and a reactive binder/matrix, and wherein the reactive/matrix binder is distributed relatively homogeneously around the core particles, and wherein the reactivity of the reactive binder/matrix is engineered by controlling the relative chemistry and interfacial surface area of the reactive components. These reactive materials are useful for oil and gas completions and well stimulation processes, enhanced oil and gas recovery operations, as well as in defensive and mining applications requiring high energy density and good mechanical properties.Type: GrantFiled: September 21, 2018Date of Patent: December 20, 2022Assignee: POWDERMET, INC.Inventors: Andrew J.
