Development of novel high temperature aluminum alloys
High temperature aluminum alloys can possess a desirable combination of specific strength, corrosion resistance, electrical and thermal conductivity, and creep resistance at temperatures in excess of 300 °C. However, the selection of commercial high temperature aluminum alloys is quite limited due to material cost and/or challenges in solidification processing of the highest performance alloys. In the present work, the high temperature aluminum alloy 8009 (Al-4.4Fe-0.6V-1.8Si, at.%) was modified to create alloys containing face-centered cubic Al (FCC-Al) and the α-phase intermetallic, and remove ...
