2. Continues of the training of using the scanning electron microscope for creating maps orientation (EBSD).
3. Training of using the circular saw.
4. Preparing the article: ‘Nucleation in Recristallization of fine-grained structure of aluminium alloy’ (for SIM 2011 conference) based on own research and articles:
- H. Jazaeri, F.J. Humphreys, The transition from discontinuous to continuous recrystallization in some aluminium alloys I – the deformed state, Acta Materialia 52 (2004) 3239–3250;
- H. Jazaeri, F.J. Humphreys, The transition from discontinuous to continuous recrystallization in some aluminium alloys II – the deformed state, Acta Materialia 52 (2004) 3251–3262;
- G.H. Zahid, Y. Huang, P.B. Prangnell, Microstructure and texture evolution during annealing a cryogenic-SPD processed Al-alloy with a nanoscale lamellar HAGB grain structure, Acta Materialia 57 (2009) 3509–3521.
5. Research
- Preparation of samples for observation in scanning electron microscope - the electrolytic-polishing by A2 reagent (test SEM / EBSD) and etching in order to observe the microstructure (for SEM);
- Preparation of the orientation maps of samples of aluminum after ECAP and recrystallization (T = 270 ° C and t = 1min, 0min.) using the EBSD / SEM – the works with other parameters than before (step 50 nm);
- Observations of the microstructure in the scanning electron microscope samples of aluminum after ECAP and recrystallization (T = 270 ° C and t = 1min, 0min.);
- Pressed by the curved channel angular (ECAP) samples of aluminum alloy (AA1050 and 3004) with dimensions 10x10x70mm using a testing machine INSTRON 3382. Samples pressed 2 -, 4 -, 6 - and 10-times using different routes between each test;
- Pressed by the curved channel angular (ECAP) samples of aluminum alloy (Al-Mg-Zr). Samples pressed once and then cut to the small samples with dimensions of 10x10x3mm by the circular saw and by the wire saw - and each of these samples will be subjected to another heat treatment (search for the appropriate temperature and time);
- Assisting in the round tensile specimens at elevated temperatures (400° C) on the testing machine INSTRON 6025.
