Production and properties of impact-resistant composites based on boron carbide and aluminum nitride

The dependence of the phase constitution and strength of B 4 C–AlN composites on the initial charge formulation and hot pressing temperature is studied. It is established that new reinforcing phases are synthesized during reaction sintering under pressure. The optimum conditions for producing B 4 C–...

Summary:The dependence of the phase constitution and strength of B 4 C–AlN composites on the initial charge formulation and hot pressing temperature is studied. It is established that new reinforcing phases are synthesized during reaction sintering under pressure. The optimum conditions for producing B 4 C–AlN composites are determined. The composites have quite high strength margin and may be used as components of armor protection in military equipment.
