Abstract
The study focused on the tensile properties of TiB whiskers reinforced β21S Ti matrix composites prepared by spark plasma sintering. TiB whiskers are synthesized by reaction sintering of TiB_2with Ti. The effect of the volume fraction of TiB whiskers on the tensile properties and morphology were studied at processing temperatures ranging from 900℃ and 1100℃. The microstructure and morphology of the in-situ TiB whiskers in the matrix were observed by scanning electron microscopy (SEM). Tensile properties, such as elevated temperature tensile strength and Young's modulus, were investigated.
