The columnar to equiaxed transition of CoCrNi medium-entropy alloy fabricated by laser directed energy deposition

The columnar to equiaxed transition of CoCrNi medium-entropy alloy fabricated by laser directed energy deposition

Understanding and revealing the evolution mechanism of the columnar to equiaxed transition (CET) that occurred in the medium-entropy alloys (MEAs)  fabricated by laser directed energy deposition (LDED) is crucial for achieving the tunable microstructure and mechanical properties. In the present work...
