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.

Why this work matters: The paper clarifies phase-selection and spinodal-decomposition behavior across a wide cooling-rate range and supports the design of cobalt-free high-performance alloys.
