OS0614 放電プラズマ焼結法で作製したTiB強化β21Sの力学的特性(先進複合材料の強度・特性評価,オーガナイズドセッション)

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.
