Query: Melting and crystallization of Sn, Bi and Pb nanoparticles in contact
  with Al   The results of studies of supercooling upon crystallization value of Bi, Sn
and Pb nanosized particles on the Al substrate and between the Al layers have
been presented. It has been shown the efficiency of usage of layered film
systems for investigation of the limiting supercooling in particle-matrix
systems with an eutectic type of interaction between components. The obtained
results have been discussed and compared with literature data.

nanorazmernyh chastic Bi, Sn i Pb na Al podlozhke i mezhdu sloyami alyuminiya.
Pokazana effektivnost ispolzovaniya sloistyh plenochnyh sistem dlya
issledovaniya predelnogo pereohlazhdeniya v sistemah chastica-matrica s
evtekticheskim tipom vzaimodejstviya mezhdu komponentami. Poluchennye rezultaty
obsuzhdeny i sopostavleny s literaturnymi dannymi.
