Properties of nanocrystalline Al-Cr-Fe-Ti alloys prepared by powder metallurgy
Original language description
Al-Cr alloys have been extensively studied because of their superb mechanical properties at elevated temperatures that can compete with steels or titanium alloys. An Al-6Cr-2Fe-1Ti (in wt.%) was prepared by powder metallurgy. Rapidly solidified powder was made by melt atomisation and compacted using hot ultra-high pressure (6 GPa). Samples were uni-axially pressed 400 °C for 1 h using hydraulic press. The purpose was to examine its structures, room and elevated temperature mechanical properties and thermal stability during static annealing and creep tests. The increased pressing temperature could have significant impact on the final structure, since it can reduce the porosity and the quality of powder particles bonding. The examined Al-6Cr-2Fe-1Ti alloy showed excellent thermal stability - its mechanical properties did not change significantly even after 100 h of annealing at 400°C. In addition, the Al-6Cr-2Fe-1Ti alloy exhibited very good creep resistance. Compared to the commercial A
