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.

A method of forming a sintered alloy, comprising:
- sintering a plurality of particles comprising Cr, the particles having a grain size of smaller than about 1000 nm prior to the sintering, to produce an alloy comprising the Cr and a second metal material, wherein:
- the Cr is present in the sintered alloy in an amount of at least about 60 at %, and
- the sintered alloy has a relative density of at least about 90%.
A sintered alloy comprising Cr and a second metal material, wherein the Cr is present in an amount of at least about 60 at %, and the sintered alloy has a relative density of at least about 90%.
A bulk alloy comprising Cr and a second metal material, wherein the Cr is present in an amount of at least about 60 at %, and the bulk alloy has a relative density of at least about 90%.
A method of forming a sintered alloy comprising a first metal material and a second metal material, comprising:
- sintering a plurality of particles to form the sintered alloy comprising the first metal material and the second metal material, wherein:
- at least a portion of the particles has a grain size of smaller than about 1000 nm prior to the sintering,
- the sintered alloy has a relative density of at least about 90%, and
- the sintering comprises pressureless sintering.
