文摘

The microstructures and textures of in-situ TiB2/Al composites are characterized quantitatively. The effects of TiB2 particles on the (sub-)grain boundaries and dislocations are characterized and discussed. The dynamic recovery and recrystallization mechanisms of in-situ TiB2/Al composites are studied.
