This paper presents a process for producing Al–Fe66Cr10Nb5B19 metallic glass composites with low residual porosity at different concentrations of components. It was found that during sintering no interphase interactions between the components of the composite occurred. The hardness and thermal conductivity of Al–Fe66Cr10Nb5B19 metallic glass composites were experimentally determined. The obtained data were compared with the values calculated according to the rule of mixtures. It is shown that the experimental values of thermal conductivity of composites with a volume fraction of metallic glass of 20 and 80% are close to the values calculated using models for parallel and series phase connection, respectively. The hardness values of these composites correspond to those calculated using the Reuss and Voigt models.
