Figure 4

Changes in sample microstructure with varying thickness. (a–c) inverse pole figure (IPFX) maps of walls from 2 to 4 hatches built with no control; axis definition and legend included; (d) melt pool depth, width and Peclet number for samples with increasing number of hatches, error bars are representative standard deviation of melt pool dimensions (as calculated in the 6 hatch sample); (e) change in primary dendrite arm spacing (standard deviation shown) and grain area of full mapped region with number of hatches; (f, g) YZ optical micrographs of 1 and 6 hatch samples, showing the outline and width of a melt pool.
