20.500.12556/DKUM-26364 Metallographic techniques for the characterization of quasicrystalline phases in aluminium alloys Several Al-alloys strengthened by quasicrystalline phases have been developed over the last few years showing the considerable potential for practical application. Therefore there is a strong need for developing new metallographic methods or adapting the traditional ones in order to identify and characterize quasicrystalline phases in a reliable, quick and economical way. This paper describes different techniques: the classical metallographic method, deep etching, particle extraction technique and cross-sectioning using focused ion beam (FIB), and discusses their advantages and disadvantages when identifying quasicrystalline particles. It was discovered that particle extraction techniques are very powerful methods for the identification of phases according to their morphology, and preparation of quality samples for X-ray diffraction (XRD). Transmission electron microscopy (TEM) analyses are also possible provided the extracted particles are thin enough. alluminium alloys quasicrystal metallography deep etching particle extraction aluminijeve zlitine kvazikristali kvazikristalinične faze true true false Angleški jezik Angleški jezik Neznano 2012-05-31 12:35:17 2012-05-31 12:35:17 2022-04-15 03:41:30 2024-01-03 03:26:26 2008 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 669.71:539 13027350 0044-2968 URN:SI:UM:DK:ZNGYF82S http://dx.doi.org/10.1524/zkri.2008.1057 1 https://dk.um.si/Dokument.php?lang=slv&id=35359 Fakulteta za strojništvo 0 0 0
