Fig. 2: Optical microscopy and EDS imaging (iron, copper), with EBSD Euler angle maps of microscopy coupons built with the interfacial plane normal to the build direction.

(Br, SS)z denotes bronze then steel being deposited in the Z-direction, and (SS, Br)z denotes steel then bronze being deposited in the Z-direction. Red Box in (Br, SS)z denotes the EDS spectrum region containing 14.15% copper by mass. Red box in (SS, Br)z denotes the melt pool region presented in Fig. 7.
