Microstructure and properties of rapid solidified Al-Si-Fe-Cr alloys

Popis výsledku v původním jazyce

Aluminium alloys belong to prospective materials finding their use in several applications like automotive or aerospace industry. The main advantages that determine these materials to be used in the wide range of application are low density and good mechanical properties. During the recycling of aluminium alloys some contamination by undesirable elements especially iron and chromium occure. The combination of low diffusivity of transition metals in aluminium and methods of rapid solidification, like centrifugal atomization, can produce alloys with increased strength and thermal stability.This work aims to prepare Al-Si-Fe-Cr alloys by centrifugical atomizer with high-speed rotating graphite disc. Prepared powders were uniaxially pressed by pressure of6 GPa to achieve more compact samples which were thermal treated at various temperatures for 100 hours and consequently compressive tested. Microstructure of powders and pressed samples was observed by electron scanning microscope.
