Characterization of the morphology of Si in the modified Al-Si alloys

One of the methods of melt-treatment of Al-Si alloys is the modification that plays a very significant role in the development of (mechanical) properties of finished product. There are a lot of well-known processes for the investigation of effectiveness of modification but an objective, exact result cannot be obtained in each case by using these methods. The method suitable for the classification of modification worked out by us was developed by integrating two methods namely the comparison by means of etalon-images and the integration of measurement of morphological parameters. This method is relatively simple, does not demand lots of measurements and gives reliable results.
