abstract = "Thermodynamic analysis of the Mg-Al-O system at 1000K confirm that Mg vapor provides extremely low oxygen partial pressure, which is enough for the decomposition of the alumina layer covering the surface of molten aluminum. The contact angle of Al on the boron carbide substrate measured under Mg vapor is sufficient for free infiltration of the ceramic preforms. The fabrication of the RBBC composites infiltrated with pure aluminum and Al-Si was successfully conducted at temperature lower 1000°C under Mg vapor atmosphere. The microstructural examination of the composites revealed the presence of newly formed ceramic phases with a good adhesion to the initial boron carbide particles. The value of Young modulus (of about 330 GPa) and hardness (of about 1400HV) of the composites only slightly depend on the Si content. The flexural strength of the composites infiltrated with Al-20%Si alloy (of about 450MPa) is higher than the reported in the literature for the reaction bonded composites. The composites fabricated at low temperature display a good corrosion resistance in humid atmosphere.",
