Development of an Al-Mn-Be-Cu alloy with improved quasicrystalline forming abilityZupanič, Franc (Avtor) Bončina, Tonica (Avtor) Rozman, Niko (Avtor) Anžel, Ivan (Avtor) Grogger, Werner (Avtor) Gspan, Christian (Avtor) Hofer, Ferdinand (Avtor) Markoli, Boštjan (Avtor) alluminium alloyscastingquasicrystalsTEMSEMAn Al94Mn2Be2Cu2 cast alloy was developed displaying increased quasicrystalline formation ability at moderate cooling rates. The as-cast microstructure consisted of a mainly icosahedral phase in the Al-matrix. The microstructure remained stable during uniform heating to 580 °C and isothermalannealing at 400 °C. Most of the icosahedral phase was preserved even after 24 h annealing at 500 °C. For that reason, this alloy presents a promising basis for further development of cast Al-alloys containing quasicrystals.20082012-05-31 12:35:13Neznano26363UDK: 669.71:539COBISS_ID: 13027094ISSN pri članku: 0044-2968NUK URN: URN:SI:UM:DK:R1E6SCQBsl
