Abstract: Nimonic 75 sheets were cold-spun under different processing conditions and then heat-treated. The microstructure evolutions occurring during the process were studied and discussed in details. The results obtained showed the feasibility of the process when adopting low values of the tool feed rate. Metal spinning produces a deformed microstructure, different in the several areas of interest of the final component. The chosen heat treatment promoted the annealing of the material across the whole part.
