Investigation on formability of bipolar plates during flexible micro forming of Cu/Ni clad foils

The formability of metal micro-parts is difficult to predict by the traditional theories because of the size effects induced by the interactive effects of specimen intrinsic and extrinsic characteristics with miniaturization. In this study, the interactive effects of different parameters on the forming quality of micro channel by flexible forming were conducted. The forming characteristic of Cu/Ni clad foils was studied from the microstructure...
