Figure 6. Dual-phase or multi-phase structures created by LST and LAM techniques: (A) The solidification process of LC-(FeCoCrNi + W) gradient composite coating and the microstructures formed in the corresponding coating layer; (B-D) Cross-sections showing the spatial distribution of face-centered cubic and laves phases of different depth of LC-(FeCoCrNi + W)^[92]. (E-L) TEM characterization of the region at a depth of 40-60 µm (E and F); 30-40 µm (G and H); 20-30 µm (I and J) and less than 10 µm (K and L) below LSR treated TiZrHfTaNb surface^[93].
