Abstract Scope |
Aluminum matrix composites (AMCs) have been extensively studied in future mobility industries because of excellent mechanical properties. Although carbon-based materials and ceramics are used as reinforcement for AMCs, they have a poor wettability with Al. To solve this, high entropy alloys (HEAs) have recently attracted a great attention as reinforcement for AMCs. They have high wettability with Al and high strength while maintaining the crystal structure.
In this study, AMCs reinforced by sub-micron Al0.5CoCrCuFeNi HEA particles were produced by powder metallurgical routes. First, HEA powder was produced by attrition milling. And then, they were subjected to thermal plasma process to make them sub-micron. 2 vol% of HEAs was then attrition milled with Al powder. The composite powder was hot-rolled and was subjected to heat treatment for 12 h at 500 °C. Reinforcing effect of Al0.5CoCrCuFeNi HEA particles on mechanical properties of AMCs will be discussed in the microstructural perspective. |
