AbstractB4C particulate-reinforced 6061Al composite was fabricated by powder metallurgy method. The as-rolled composite possesses high tensile strength which is comparable to that of the peak-aged 6061Al alloy. More importantly, the microstructures and mechanical properties are thermally stable during long-term holding at elevated temperature (400 degrees C). The microstructual contributions to the strength of the composite were discussed. Transmission electron microscopy (TEM) analysis indicates that the in-situ formed reinforcement Mg(Al)Bs(2) as products of the interfacial reactions between B4C and the aluminum matrix. show not only good resistance to thermal coarsening but also strong pinning effect to the grain boundaries in the alloy matrix.
