Effect of Molybdenum Additions on the Structure of TiB 2 –(Fe–Mo) Composite Materials

To examine the effect of molybdenum additions on the structurization of TiB2–(Fe–Mo) composite materials, differential thermal analysis of the samples with 8, 13, and 20 wt.% Mo in the metallic phase was carried out and their structure was examined after sintering. It is shown that molybdenum is an active component in the systems with 8 and 13 wt.% Mo and promotes the formation of complex Mo2FeB2 borides, which additionally strengthen the material. When the molybdenum content of the metallic phase increases to 20 wt.%, boride compounds intensively form in the system, making the composite material brittle.
