Abstract:In ternary Al-Mn-Be alloys a metastable quasicrystalline phase can form at relatively low cooling rates (≈ 100 K/s); however, besides the quasicrystalline phase other phases can also be present. We found that the investigated alloy is very prone to the formation of metastable phases, which are also quasicrystalline. Using different investigation methods we determined the type of phases, their shape, morphology, chemical composition and distribution. Special attention was given to the micro- and nano-sized quasicrystalline particles. When using slow cooling, Al10Mn3 and Be4AlMn were present; however, with a faster cooling rate a quasicrystal approximant and a quasicrystalline phase were formed.

Title:Vpliv ohlajevalne hitrosti na mikrostrukturo zlitine Al-Mn-Be
Abstract:V ternarnem zlitinskem sistemu Al-Mn-Be lahko nastane metastabilna kvazikristalna faza pri relativno majhni ohlajevalni hitrosti (≈ 100 K/s), vendar lahko poleg nje nastanejo še druge kristalne faze (predvsem intermetalne faze). Z uporabo različnih raziskovalnih metod smo ugotovili vrsto nastalih faz, kemijsko sestavo in porazdelitev. Ugotovili smo, da je zlitina nagnjena k nastanku metastabilnih faz (tudi kvazikristalnih). Predvsem so zanimivi kvazikristalni delci, ki se pojavljajo v mikro- in nanometrskih velikostih. S počasnim ohlajanjem so nastale faze Al10Mn3 in Be4AlMn, pri hitrem ohlajanju pa so se namesto njih pojavili kvazikristalni aproksimanti in kvazikristalne faze.
Keywords:aluminij, kvazikristali, ohlajevalna hitrost, mikrostruktura
