Interaction between Fe–Ti–B4C Powder Charge Components During Heating
The structurization of compacted Fe–Ti–B 4 C powder mixtures during reaction synthesis is studied. X-ray diffraction of the material synthesized at 1200°C shows the presence of TiC and TiB 2 phases formed in the interaction of titanium with carbon and boron resulting from the dissolution of B4C part...

Summary: | The structurization of compacted Fe–Ti–B
4
C powder mixtures during reaction synthesis is studied. X-ray diffraction of the material synthesized at 1200°C shows the presence of TiC and TiB
2
phases formed in the interaction of titanium with carbon and boron resulting from the dissolution of B4C particles in the liquid phase and the interaction of iron with boron. The reaction between titanium, iron, and carbon (boron) is accompanied by a significant exothermic effect confirmed by the presence of two exothermic peaks on the DTA curve at 1085°C (corresponding to the eutectic formed in the Fe–Ti system in the interaction of respective mixture particles on contact surfaces) and 1236°C (resulting from the formation of titanium diboride and carbide particles from the liquid phase). |
