Figure 420

Bright field photomicrograph of an etched polished cross section of the welding zone of an experimental sample. See the dendritic microstructure and small grains due to recrystallization in the heat-affected zone (HAZ) generated by flow fusion welding. The outlines of dendrites appear brown; the interdendritic space is filled with eutectoïd phase alfa + delta (in blue). Sample E66, binary bronze CuSn10. See Azéma et al. 2012; Azéma and Mille 2013a.
