N2 - Microstructure, texture and topography have been studied in a recrystallized Ni–5at.%W substrate before and after additional annealing at 1025C for 1 h. The initial recrystallized material contained a strong cube texture and a high fraction of low angle grain boundaries. R3 boundaries were also frequent in this<br/>substrate, including both coherent and incoherent twin boundary segments as well as non-twin R3 boundaries formed between twins and non-matrix neighbors of the cube texture component. A strong correlation between the boundary type and the average depth of grain boundary grooves was observed<br/>in this material. The smallest average groove depth was obtained for coherent twin boundaries, followed by low angle boundaries. Significantly greater average groove depths were found for the other boundary types. A similar correlation was also observed between the boundary type and the average inclination angle of groove walls. The additional annealing resulted in grain growth, texture strengthening and an increase in the fraction of low angle boundaries. Also, changes were observed in the extent of thermal grooving studied in the same regions before and after the additional annealing. Groove depths increased for a large number of stationary boundaries, whilst the majority of migrating boundaries developed shallower grooves compared to those before the additional annealing.
