EFFECT OF MOLYBDENUM ADDITIVES ON THE STRUCTURE OF TIB₂–(Fe–Mo) COMPOSITE MATERIALS

Abstract

To examine the effect of molybdenum additives on the structurization of TiB₂–(Fe–Mo) composite materials, differential thermal analysis of samples with 8, 13, and 20 wt.% Мо in the metal phase was carried out and their structure was studied 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 reinforce the material. When the molybdenum content of the metal phase increases to 20 wt.%, boride compounds intensively form in the system, making the composite material brittle.
