Abstract

Al-2Mn-5Fe alloy (wt.%) was prepared in a graphite crucible under vacuum atmosphere. Al-2Mn-5Fe alloy melt was first obtained in a hot filling furnace and then directionally solidified upward with different growth rate ranges (8.3–978 μm/s) at a constant temperature gradient (6.7 K/mm) in the Bridgman-type directional solidification furnace. Variations of electrical resistivity () for casting samples with the temperature in the range of 287-574 K were also measured by using a standard dc four-point probe technique. The enthalpy of fusion and specific heat for same alloys were determined by means of differential scanning calorimeter (DSC) from heating trace during the transformation from solid to liquid.
