Microstructural evolution and high-temperature oxidation resistance of laser-modified AlCoCrFeNi(YHf) high-entropy alloy at 1200 °C

The Y/Hf-doped equiatomic AlCoCrFeNi high-entropy alloy (HEA) shows good oxidation resistance but suffers from Al depletion and oxide layer spallation during long-term exposure at 1200 °C. In this study, nanosecond laser remelting was employed to regulate the surface microstructure and diffusion beh...
