The Kirkendall effect describes the movement of the boundary between two diffusing species caused by unequal atomic fluxes, leading to net vacancy injection and void formation. At the nanoscale, this ...
The interdiffusion of Ni and W results in the formation of Ni 4 W as an intermetallic layer. At the interface between the Ni 4 W layer and Ni phase, Kirkendall voids are observed. Figure 1. Kirkendall ...
