Using example powders such as those of tungsten, molybdenum and niobium, the authors establish that ultradisperseed media show reductions in melting point and in polymorphic transition and sintering temperature along with increases in diffusion coefficient and chemical activity as a consequence of the material energy being in excess of that for the equilibrium condensed media. Such an excess-energy material can result from dispersal, quenching, deformation, or irradiation.
