Boron fiber reinforced Ti matrix composites were fabricated by a pulsed current hot pressing (PCHP) process at various holding temperatures between 973 K and 1273 K at pressure of 32 MPa for 600 s. Well bonding between the fiber and matrix was obtained by the PCHP at 1073 K. When fabricated at the holding temperature higher than 1173 K, a TiB 2 layer was formed along the interface between the fiber and the matrix, and the crystallization of boron in the vicinity of tungsten core in the fiber oc curred. The thickness of TiB 2 layer formed and the crystallized boron increased with increasing the holding temperature. Tensile tests were carried out at room temperature for the composites fabricated by the PCHP at 1073 K. The yield stress of the compo sites containing 17.2 vol÷ boron fiber was attained at 706 MPa. This value was about 80÷ of the yield stress calculated by the force equilibrium equation of a composite along with the fiber axis direction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
