Preparation and properties of CNTs-Ti_3Al/B_4C composites

摘要

CNTs-TiAl/B_4C composite has been obtained by high energy ball milling and hot press sintering. These technical process promoted the solid reaction and resulted in the formation of composites comprising Ti-Al, TiC, TiB_2 and B_4C. The SEM images and measurement of the mechanical properties proved that the addition of 1.5wt.% CNTs further improves the fracture toughness and the bending strength of TiAl/B_4C composites.
