Notes:
Boron-fiber-reinforced Al-matrix composite was fabricated by a pulsed current hotpressing (PCHP) process at a pressure of 32MPa for 600s. It was found that the boron fiber andthe Al-matrix were well bonded when the PCHP process was performed at a holding temperature of773K. No interfacial reaction layer was observed along the interface between the boron fiber andthe matrix when PCHP was done at 773K for 600s. Tensile deformation carried out at roomtemperature for the composite showed that the tensile yield stress increased with increasing volumefraction of the boron fiber in the composite. The composite with 17.2 vol.% of boron fiberpresented a tensile yield stress of 600MPa. This value was about 90% the yield stress estimated bya force equilibrium equation of a composite taking into account the direction of fiber axis
