Microstructure and properties of 6FeNiCoSiCrAlTi high-entropy alloy coating prepared by laser cladding

▶ The 6FeNiCoSiCrAlTi high-entropy alloy coating with simple BCC solid solution phase has been successfully laser cladded on a low carbon steel substrate. ▶ The tendency of component segregation in the solidification microstructure of multi-component alloy is effectively relieved by laser cladding. ▶ There are lots of abnormal low angle grain boundaries distributed in the coatings. ▶ The coating shows high microhardness and excellent soft magnetic properties.
