Abstract:

In this study, the effect of scrap ratio on the mechanical and corrosion properties of Zr-1Nb-0.7Sn-0.1Fe alloy was studied. Oxygen content in the ingot cake increased rapidly with increasing fraction of scrap, which can be attributed to the surface oxide of scrap cake made of small pieces of turning, chips, etc. Iron content was not changed much, suggesting scrap materials was well reserved in the iron-free container. As-cast structure of Zr-1Nb-0.7Sn-0.1Fe alloy with the scrap:sponge ratio displayed basket-weave α phase and no appreciable change of the cast structure was observed with change of scrap fraction. The strength increases with increasing fraction of scrap, which can be attributed to the increase of oxygen content. The ductility decreased slightly with increase of scrap fraction. The increase of oxidation resistance with increasing fraction of scrap also can be linked to the increase of oxygen content.
