The invention is a procedure for dynamical deep etching and extraction of particles from aluminium alloys for sample preparation, and characterisation of Al-alloys using scanning and transmission electron microscopy, and X-ray diffraction. Results are two types of samples: deep-etched surface of a bulk sample and extracted powders. The invented procedure enables that the dissolution takes place in whole sample volume, only Al-matrix being dissolved, other phases remain chemically and geometrically the same, and no dissolution products remain in the sample.
F.01 Acquisition of new practical knowledge, information and skills
COBISS.SI-ID: 14779414The textbook describes heat treatment of different metallic materials. At the beginning, foundations of heat treatment are explained, which are necessary for understanding and application of heat treatment. In the subsequent chapters, the most important heat treating procedures are explained, with numerous examples for the commercial alloys.

COBISS.SI-ID: 67806721This work presents development of aluminium alloys which posses complex intermetallic phases; that is in this case quasicrystals. In quaternary phase system aluminium rich phase system Al-Mn-Be-Cu influence of alloying elements on microstructure development was investigated. To achieve this several alloyswith similar chemical composition was casted under different solidification conditions. Investigations based on well known stable state phase system Al-Mn-Cu and previous results of beryllium influence in Al-Mn system. With help of different chemical, microstructural, structural and thermodynamical analysis microstructure and its development was determinated. For determination of critical cooling rate for formation of metastable quasicrystals, different thermoelements monitored the temperature dynamic in the regions of interest. Behaviour of quasicrystals and its influence during plastic deformation was investigated on basis of nanoidentation and compressive tests.
