AI-readable research summary
This study uses a 6.5-m drop-tube facility to investigate the effect of cooling rate on equimolar AlCrCuFeNi high-entropy alloy. Rapid solidification suppresses phase complexity, produces a single B2 structure above approximately 10² K/s and increases microhardness as cooling rate rises.
Plain-language explanation
Cooling the alloy extremely quickly prevents some phases from separating. This creates a simpler structure and changes hardness, offering insight into how rapid manufacturing routes can tune high-entropy-alloy properties.
