摘要：

The study focuses on the development of lightweight nanocomposites using a powder metallurgy route. Y2O3 nanoparticles (1, 2, and 3 wt%) are added to an AlCrFeNiTi high-entropy alloy (HEA) matrix. The addition of Y2O3 nanoparticles leads to the formation of a small intermetallic phase in HEA matrix. With increasing Y2O3 wt. %, the size of the crystallites diminishes starting from 32.7 nm (HEA) to 10.3 nm (HEAnC-3). TEM examination reveals that the alloy is nanocrystalline with an average grain size of 39.2 +/- 2.1 nm. DSC study indicates that the nanocomposites are stable up to 1000 degrees C, making them ideal for high-temperature applications.
