Table 2 shows the relative density values of all sinteredcomposites. It can be seen that the relative density decreasedslightly as the volume fraction of HEA particles increased. Duringsintering, the filling of pores mainly depended on the viscous flowof glassy powders. Therefore, the increase of HEA particles made itmore difficult to fill the pores completely. Regarding metallic glasscomposites with various volume fractions, typical diffraction patterns of BCC HEA phases were superimposed on broad halos ofthe glassy matrix
