The solid-state reactions in the Al–15 and 50 at% MgB2 composite materials occurred between the MMed powders and process control agent (PCA) after heating at 773–873 K for 24 h. The products of the solid-state reaction induced Al3BC, AlB2, γ-Al2O3 and spinel MgAl2O4. MM processing time and heating temperatures in the Al–15 and 50 at% MgB2 composite materials affected the selection of those intermetallic compounds. When MM processing time was increased for a given composition, the formation of the Al3BC compound started at lower heat treatment temperatures. However, when the amount of MgB2 was increased in the 4 h MM processing regime, the formation of the Al3BC compound during heating was suppressed. As a result of the solid-state reactions in MMed powders the hardness was observed to increase after heating at 573–873 K for 24 h. The fully dense bulk nano-composite materials have been successfully obtained through the combination of the MM and spark plasma sintering (SPS) processes for the 4 h or 8 h MMed powders of the Al–15 at% MgB2 composite materials sintered under an applied pressure of 49 MPa at 873 K for 1 h.
