Room temperature tensile fracture characteristics of the oriented TiB whisker reinforced TA15 matrix composites fabricated by pre-sintering and canned extrusion

摘要

In situ oriented TiB whisker reinforced TA15 matrix composites (TiBw/TA15) exhibited an improvement of tensile properties. The strain hardening after yield point was almost counteracted by the reduced effective cross-sectional area caused by the whisker fracture, thus resulting in a large yield strength ratio.
