The mechanical properties of a unique, dispersion-strengthened aluminum alloy, which contains scandium (Sc) are described. The alloy, named Pandalloy® Gen2, is produced by vacuum hot pressing of atomized powders that were rapidly solidified at cooling rates of 103 to 105 °C per second. Rapid solidification creates fine, intermetallic particles that are dispersed throughout the aluminum matrix. The particles are composed of combinations of Al, Gd, Ni, Sc, and Zr, which solidify as intermetallic phases that are resistant to coarsening and result in superior room and elevated temperature strength up to 700 °F (371°C) and higher, compared to conventional heat treated aluminum alloys such as AA2618-T61. Initial application of Pandalloy® Gen2 is focused on race car pistons where advantages of high tensile and fatigue strengths, excellent thermal stability and resistance to cracking, can be used to achieve higher combustion cylinder temperatures, greater horsepower and increased durability of pistons.
