Abstract
By means of neutron-diffraction ten Al-Si-alloys, Al, and Si were investigated in the molten state. Structure factors and atomic distribution curves were obtained. An improved method for the evaluation of the concentration dependency of the measured coordination number is given. Regarding also the result of thermodynamic measurements, the following model for Al-Si-melts was derived: The melts contain besides Al- and Si-atoms with statistical distribution Si4-Tetrahedra, whose concentration dependency is given. The Si4-concentration versus composition curve shows a steep increase between 40 and 50 at. % SiKeywords
