Influence of metallic dopants on fracture behaviour of TiB2 based cermets
Original language description
Titanium diboride (TiB2) - metal composites were prepared by hot-pressing of the TiB2 - Ni and Ta doped TiB2-Ni powders. The obvious limitation of pure TiB2 is the bad sinterability, exaggerated grain growth at temperatures exceeded 2000°C needed for thedensification and brittleness. There is only limited number of approaches how to improve fracture resistance. The method used in this work is based on doping the basic microstructure by above mentioned metals. The positive influence of dopants on the microstructure and fracture behaviour was demonstrated by means of mechanical properties and fractographic analysis. The right selection of dopants led to the refinement of microstructure resulted in the increase of flexural strength up to the level of 700MPa and fracture toughness of 5.0 MPa.m1/2.
