Abstract
Superplastic deformation of coarse-grained (TiB + TiC)/Ti-6Al-4V composite was carried out at 840-980 °C and 10â4 to 10â2 sâ1 in comparison with that of Ti-6Al-4V alloy. The composite had the same optimum superplastic temperature and strain rate as Ti-6Al-4V alloy did. A maximum elongation 462% of the composite was obtained at 920 °C and 10â3 sâ1. Based on the microstructure evaluation and the value of activation energy, superplastic mechanism and accommodation mechanism in superplastic deformation of the composite was discussed.
