The results of studies of the effect of pressure HIP 0.7 GPa on the physical properties of powders reinforced ceramic materials with a matrix of lanthanum hexaboride (LaB6) and core fibers of titanium diboride (TiB2). It is found that the HIP pressure reduces in the matrix phase of the composite material voltages AB 2 type and somewhat increases the value of the lattice parameter. It is shown that this may be related to the mechanisms of powder densification during HIP. Keywords: borides, reinforced materials, pressure, structure, microtension lattice parameter.
