| Abstract Scope |
Aluminum alloys are relatively inexpensive and offer an exceptional strength-to-weight ratio and high thermal conductivity, making them well suited for heat exchangers for aerospace applications. However, mechanical properties like ultimate tensile strength, fatigue life and creep strength of most common Al-alloys deteriorate at elevated temperatures. Al-Ca-Ce alloys may be a solution with low density, high thermal conductivity, and good thermal stability. However, little is known about the microstructure and thermal stability of ternary Al-Ca-Ce alloys. In this research, we explore the microstructures of cast Al-Ca-Ce alloys to understand the coarsening behavior of the formed dispersoids and hardness retention of the alloy. We also study the different phases formed in this system with relevant characterization techniques and compare the experimental results with computational thermodynamic predictions. |
