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.

预烧结和罐装挤压制备的定向TiB晶须增强TA15基复合材料的室温拉伸断裂特性

原位取向TiB晶须增强的TA15基体复合材料（TiBw / TA15）表现出拉伸性能的改善。晶须断裂导致的有效横截面减小，几乎抵消了屈服点后的应变硬化，从而导致了较大的屈服强度比。
