Abstract
Rapid solidification (RS) of Al -TM alloys (TM:Fe, Ni, Mn), combined with following mechanical consolidation of RS flakes was used to produce highly refined structure of the materials. RS flakes were manufactured using spray deposition of the molten alloy on the rotating water-cooled copper roll. The preliminary consolidation of the RS-flakes was performed at 320 degrees C by means of vacuum compression and 100-tonn press. As-compressed billets were then extruded at 400 degrees C using extrusion ratio lambda = 19. Mechanical properties of as-extruded materials were examined at 20 degrees C - 550 degrees C by compression tests performed at constant true strain rate of 5.10(-3) (s(-1)). It was found that the most effective strengthening of RS materials result from combined dispersion strengthening related to highly refined constituent particles and solid solution strengthening due to Mg addition. The effect of increased mechanical properties is pronounced at low and intermediate deformation temperatures, while at elevated temperatures deterioration of the properties is observed. Structural observations confirmed beneficial influence of the rapid solidification on an effective refining of intermetallic compounds, which is particularly visible for alloys with high concentration of transition metals.
