Structure and Properties of the Al–1% Ca–0.5% Fe–0.25% Si–0.5% Zr Alloy Produced via Casting in an Electromagnetic Crystallizer

Abstract

Abstract The structure, mechanical properties, and electrical resistivity of a cold-rolled wire made of the Al–1% Ca–0.5% Fe–0.25% Si–0.5% Zr alloy produced via casting in an electromagnetic crystallizer are analyzed. A heat-resistant wire made of the alloy Al–7% REM (01417), which was developed for the granular technology of powder metallurgy (RS/PM), is used as a reference. It is shown that the addition of calcium in the presence of iron and silicon makes it possible to obtain a phase composition that provides a thermal stability of up to 300°C inclusive.
