摘要：

In situ Ti/TiB composites (Ti-6Al-4V matrix reinforced with TiB phase) with different volume fractions of the TiB phase, have been produced by consolidation of rapidly solidified Ti-6Al-4V alloys with different levels of boron addition. The microstructural examination of such composites shows that the reinforcing phase has a fine grain size and a uniform distribution throughout the matrix. The Young's moduli of the in situ composites have been determined experimentally to study the strengthening effect of the TiB phase. It was found that the Young's modulus of an in situ composite with 10 vol % TiB phase can be increased to 140 GPa, compared to 116.7 GPa for the matrix alloy. The theoretical predictions are in good agreement with the present experimental results and other results of similar composites obtained by the reactive sintering technique.
