Title:
熱安定化ニッケル－コバルト材料及びこれを熱安定化する方法
Document Type and Number:
Japanese Patent JP7250717
Kind Code:
B2
Abstract:
Nickel-cobalt materials, methods of forming a nickel-cobalt material (902), and methods of thermally stabilizing a nickel-cobalt material (902) are provided. A nickel-cobalt material (902) may include a metal matrix composite with amorphous regions (706) and crystalline regions (702) substantially encompassed by a nanocrystalline grain structure (104) with a grain size distribution of about 50 nanometers to about 800 nanometers, and the nanocrystalline grain structure (104) may include widespread intragranular twinning (404). The metal matrix composite may have a chemical makeup that includes nickel, cobalt, and a dopant such as phosphorus and/or boron. A nickel-cobalt material (902) may be heat treated within a first temperature zone below the onset temperature (506) for grain growth (908) and then within a second temperature zone above the onset temperature (506) for grain growth (908) in the material (902). Chemical composition and heat treatment may yield a thermally stabilized nickel-cobalt material (902).
