2. Surface preparation of three samples (grinding on abrasive papers and polishing) and a study of the microstructure in the scanning electron microscope (FEI XL30 E-SEM) Aluminum alloy with 2.7% magnesium and 0.5% zirconium to confirm the well-selected saturation temperature and aging . Three samples were saturated at a temperature of 610 ° C and cooled in water and in turn each of them has been tempered by annealing at 300 ° C separately for 1, 3 and 24 hours. Observation of each of the microstructures revealed no precipitation, so it may be the treatment process parameters were not properly matched or separation is so small that the resolving power of microscope used was insufficient. Measurements will be repeated on a different microscope.
3. Stady of the book which has been bought to the project:
Haldar, Arunansu; Suwas, Satyam, Bhattacharjee, Debashish (eds.), Microstructure and texture in steel and other materials, Springer Publishing, London 2009. It contains materials from the International Conference under the same title (held 5-7.02.2008r. in Jamshedpur, India) and it consists of six chapters, headed respectively: Introduction, Control of Texture and Microstructure in Steels, Modeling, Specialized Characterization Techniques Texture and Microstructure Development During Special Processes and Materials, Contributory Papers, which in the first place are the most interesting chapters I, II, V and VI.
