Chemical order of manganese-antimony liquid alloys obtained experimentally by the neutron null matrix method

摘要: The Bhatia-Thornton concentration-concentration partial structure factor S CC ( q ) is a strong indicator of the order in liquid alloys. Manganese one four metals, which has negative neutronic scattering length, while antimony positive. Thus for defined composition (Mn 60 Sb 40 linear combination two lengths weighted by atomic compositions zero (zero alloy). We present here results neutron diffraction on Mn "null matrix" alloy at 950°C, proportional to ("null method). total 800°C also been measured. main peak experimental proof chemical this alloy. This confirmed real space Fourier transform factor. To interpret our results, generally uses effective potentials determined with pseudopotential formalism. But transition metal p...
