First claim
Opening claim text (preview).
What is claimed is: 1. A nickel-cobalt material, comprising: a nanocrystalline grain structure with a grain size distribution of about 50 nanometers to about 110 nanometers, the nanocrystalline grain structure comprising phosphorous precipitates at nanocrystalline grain boundaries and intragranular twinning, the material having a chemical makeup comprising from about 25% to about 40% by atomic weight cobalt, from about 1,000 ppm to about 3,500 ppm by atomic weight of phosphorous or boron, and nickel. 2. The nickel-cobalt material of claim 1 wherein nickel forms the balance of the material. 3. The nickel-cobalt material of claim 1 wherein fatigue crack resistance in the nickel-cobalt material is increased with reduced nanocrystalline grain size. 4. The nickel-cobalt material of claim 1 , wherein the nickel-cobalt material exhibits a Vickers hardness greater than 400 Hv. 5. The nickel-cobalt material of claim 1 wherein the nickel-cobalt material exhibits a fracture toughness of about 10 MPa·m 1/2 to 70 MPa·m 1/2 . 6. The nickel-cobalt material of claim 1 wherein the nickel-cobalt material exhibits an increased thermal stability with an onset temperature of about 50% or 60% of the melting temperature for the material. 7. The nickel-cobalt material of claim 1 wherein the nickel-cobalt material exhibits an ultimate tensile strength of from about 1,000 MPa to about 1,500 MPa. 8. A component, comprising: a body wherein at least a portion thereof includes a thermally stabilized nickel-cobalt alloy with nanocrystalline grain structures, pinning and intragranular twinning that exhibits fracture toughness of about 10 MPa·m 1/2 to 70 MPa·m 1/2 , an increased thermal stability with an onset temperature of about 50% or 60% of the melting temperature for the alloy, and an ultimate tensile strength of from about 1,000 MPa to about 1,500 MPa, wherein the nickel-cobalt alloy includes a chemical makeup comprising from about 30% to about 35% by atomic weight cobalt, from about 1,000 ppm to about 1,500 ppm by atomic weight of phosphorous or boron, and nickel as the balance of the material. 9. A component, comprising: a body wherein at least a portion thereof includes a thermally stabilized nickel-cobalt alloy with nanocrystalline grain structures, pinning and intragranular twinning that exhibits fracture toughness of about 10 MPa·m 1/2 to 70 MPa·m 1/2 , an increased thermal stability with an onset temperature of about 50% or 60% of the melting temperature for the alloy, and an ultimate tensile strength of from about 1,000 MPa to about 1,500 MPa, wherein the pinning comprises phosphorous precipitates at boundaries between the nanocrystalline grain structures. 10. The component of claim 9 wherein the nanocrystalline grain structures include a grain size distribution of about 50 nanometers to about 110 nanometers.
