НОВЫЙ ТИП СПЛАВОВ Al-Si-Mg Ca С РАЗЛИЧНЫМИ Са И ИХ ИНДЕТИФИКАЦИОННОЕ ИСПОЛЬЗОВАНИЕ ДЛЯ ЦВЕТНОЙ МЕТАЛОГРАФИИ

 

Abstract. Aluminum and aluminum alloys application area is very wide and future uses of aluminum alloys are connected with further development of new alloys, but primarily with production technology and processing. The article presents some analysis of Ca influence considering amount variations such as 0,1% to a 1% Ca in order to offer the optimal amount to achieve desired technological, chemical and mechanical properties. The analysis of new alloys overall structural analysis an separate components identification of new Ca alloy structures using of the color metallography will be also undertaken. The application of color metallography is possible to differentiate and identify the presence of the intermetallic particles with different chemical composition.
Keywords: alloy Al-Si-Mg, color contrast, master alloys, alloying.
