Abstract
The density and thermal expansion coefficients of polycrystalline, liquid and amorphous phases of Fe60Co20Si8B12 alloy in the temperature range of 293÷1650 K have been measured by the monochromatic gamma-ray attenuation technique. The features of crystallization of the melt and amorphous film have been investigated. Reference tables of properties have been developed, their errors have been estimated, and approximation equations have been obtained.
