%X L12 precipitate-hardened high-entropy alloys (HEAs) and medium-entropy alloys (MEAs) exhibit outstanding mechanical properties. A comprehensive understanding of L12 precipitate behavior is essential to optimize the mechanical performance of these alloys. In this study, the precipitation behavior and corresponding mechanical properties of a (CoCrNi)94Al3Ti3 MEA were systematically investigated under various aging treatments. Aging at 900°C significantly improved the strength–ductility balance compared to conventional L12-hardened MEAs. In particular, the specimen aged at 900°C for 1 h showed an ultimate tensile strength (UTS) of 1102 MPa, a yield strength (YS) of 632 MPa, and an elongation (EL) of 45.7
