Abstract

Aluminium alloys are frequently used structural materials. Their properties can be affected by manufacturing method. Melt spinning is very promising method, enabling to obtain finer structure and increased hardness. In this work, Al - 11Fe and Al - 7Fe - 4Cr alloys were investigated. They were prepared by conventional casting, melt spinning method, and hot pressing, respectivelly. Subsequently the microstructure was investigated using scanning electron microscopy (SEM), the hardness was measured by Vickers method and thermal stability was analyzed by long-term annealing. By comparing the alloy of Al - Fe with Cr doped Al – Fe alloy it was found that the method of production strongly affects the microstructure; the hardness of the alloy has been increased. The alloying element used shown an additional positive effect on properties improved by production technology.

Keywords: Aluminium alloys, melt spinning, thermal stability, microstructure
