Abstract
Provided in one embodiment is a method, comprising: sintering a plurality of nanocrystalline particulates to form a nanocrystalline alloy, wherein at least some of the nanocrystalline particulates may include a non-equilibrium phase comprising a first metal material and a second metal material, and the first metal material may be soluble in the second metal material. The sintered nanocrystalline alloy may comprise a bulk nanocrystalline alloy.
Claims29
A method comprising:
- sintering a plurality of nanocrystalline particulates to form a nanocrystalline alloy;
- wherein
- at least some of the nanocrystalline particulates comprise a non-equilibrium phase comprising a first metal material and a second metal material;
- and
- the first metal material is soluble in the second metal material.
A method comprising:
- sintering a plurality of nanocrystalline particulates to form a nanocrystalline alloy;
- wherein
- at least some of the nanocrystalline particulates comprise a non-equilibrium phase comprising a first metal material and a second metal material;
- and
- the sintering involves a first sintering temperature, and the first sintering temperature is lower than a second sintering temperature needed for sintering the first metal material in the absence of the second metal material.
A sintered nanocrystalline alloy comprising at least one of W and Cr, wherein the nanocrystalline alloy has a relative density of at least about 90%.
