The dependence of the elastic modulus, porosity and mechanical properties on different hafnium contents in the system was shown. It was shown that despite the complete completion of the sintering processes at a temperature of 1250 °C, significant residual porosity was observed in the materials. Thus, in the Zr-Ti-Nb alloy, it was within 5.4-5.8%. When 5% HfHx was added to the powder mixture, the porosity increased to 8.4-9.3%. With a further increase in the amount of hafnium hydride in the powder mixture to 10%, the residual porosity was 8.0-8.4%. A further increase in hafnium to 15% leads to a decrease in the residual porosity to values ​​of 4.9-6.3%. It was determined that for the Zr-Ti-Nb system it was 69.30 GPa. When 5% HfHx was added to the initial powder mixture, this figure was 75.15 GPa. With a further increase in HfHx to 10%, the elastic modulus dropped to 71.51 GPa, and with the addition of 15%, a drop in Young's modulus values ​​to 64.72 GPa was observed.
