Popis:	A comparison between rapidly quenched magnesium and two eutectic binary magnesium alloys is presented. The data show clear shift toward smaller grains using the metal additive. Furthermore the Mg89Sn11 alloy shows considerably higher thermal stability and for shorter periods can withstand also temperatures over 350 °C. In all cases a gradient of crystal grain size has been observed as a result of poor thermal conductivity of the liquid metal. The current results could help to develop a magnesium based metal alloy for hydrogen storage.A comparison between rapidly quenched magnesium and two eutectic binary magnesium alloys is presented.
