| Abstract: | The paper examines how the grain-size composition of starting titan diboride powders and calcium silicon and calcium hexaboride additives influence the consolidation of titanium diboride in hot pressing and the structure and properties of hot-pressed materials. It is shown that 3 and 5 wt.% of calcium silicon decrease the pressing temperature by 200 °C, refine the structure, and improve the density and mechanical properties of titan diboride materials. |
