Abstract/OtherAbstract:
|
A tetragonal σ phase of the equiatomic FeCr alloy was investigated by x-ray diffraction under pressure up to 77 GPa. The phase was found to be stable in the whole pressure range studied. The equation of state for the tetragonal phase was found to have a value of bulk modulus K(0) = 217(5) GPa and its pressure derivative was K(0)' = 5.8(2), which makes it less compressible than the constituent elements. Electronic factors governing the σ phase stability are discussed in relation to the Hume-Rothery mechanism. |
