Change of the casting magnesium alloys structure during the melt solidification on rotating heat receiver

Using the methods of metallography, measurements of mechanical properties and X-ray analysis, we investigated the effect of rapid quenching by the method of extracting a hanging melt drop for casting alloys belonging to the Mg-Al-Zn (ML-5) and Mg-Nd-Zr (ML-10) systems. It is shown that the strength of the fibers significantly exceeds the ones values inherent for these materials, especially for the alloy ML-10, what is associated with the presence of a favorable preferential orientation of the rapidly crystallized fibers after rapid crystallization.
