TEM study of interfacial layers in Nb-clad stainless steel
EMSL Project ID
29403
Abstract
Nb-clad 304L stainless steel manufactured by cold rolling is currently under consideration for use as a bipolar plate material in polymer electrolyte membrane fuel cell stacks. To make the fabrication of bipolar plates using the Nb-clad SS feasible, annealing may be necessary for the Nb-clad SS to reduce the springback induced by cold rolling. However, the annealing can develop interfacial layers between the Nb cladding and the stainless steel core. Our previous study has shown that the interfacial layers play a key role in the failure of the Nb-clad stainless steel. Thus, it is of technological importance to identify the nature of the interfacial layers using transmission electron microscopy.
