Forced SHS Compaction of TiB 2 –Ti: Structure and Properties
International Journal of Self-Propagating High-Temperature Synthesis（2023）
摘要
TiB 2 –Ti metal–ceramic composites were produced by forced SHS compaction. The influence of superstoichiometric amount of Ti (6–20 wt %) relative to TiB 2 on the regularities of combustion and phase composition/structure formation of TiB 2 –Ti composites was studied. It was shown that the phase composition of composites is inconsistent with the Ti–B phase diagram. The microhardness of composites was determined to drop from 34 to 18 GPa with increasing the binder content. Cutting properties of composites were evaluated.
