СТАБИЛЬНОСТЬ К ТЕМПЕРАТУРНЫМ ВОЗДЕЙСТВИЯМ КВАЗИКРИСТАЛЛОВ Al–Co–Ni И Al–Cu–Fe ПРИ ПРОПИТКЕ КОМПОЗИЦИОННЫХ МАТЕРИАЛОВ

Abstract

The heat capacity of decagonal and icosahedral phases quasicrystals of the Al–Co–Ni or Al–Cu–Fe alloys was calculated at the high temperatures. The deviation of heat capacity from the 3R Dulong-Petit value is observed, which means that these phases are stable, and decagonal phase is more stable.
