Conclusions

  1. 1.

    A study was made of the effects of small additions (0.05–1.0 wt.%) of the iron-group metals upon the sintering of niobium and of some properties of the resultant alloys.

     
  2. 2.

    The hypothesis is advanced that Fe, Co, and Ni additions activate the sintering of niobium by bringing about localization of the free electrons of the niobium atoms in the 3d states, as a result of which the amount of free energy stored in the system niobium-addition metal diminishes. Nickel — the metal whose 3d level has the highest acceptor capacity — exerts the strongest activating influence.
