Surface rolling extrusion processing is applied to reconstruct the microstructure of U–5.7Nb alloy. A micro–nano structure layer formed on surface, at same time inclusions in surface are also refined and uniformity niobium element distribution improved. The corrosion resistance test indicates that, rate material accelerated, but stability oxide film alloy after better. modified with uniform by can eliminate uneven potential turning, thereby improves local
