Fig. 9. a Illustration of Ti-6Al-4V solidification map, showing that columnar β grains and equiaxed β grains can be obtained via controlling temperature gradient (G) and solidification rate (R). The different color shapes in a illustrating G vs. R in different sites of 2-bead wall during deposition in b
