Abstract
This paper presents the development of an ultra-fine grained (UFG) microstructure in Nb1Zr alloy through severe plastic deformation by accumulative roll bonding (ARB). The sheets were subjected to 5 ARB cycles, for a total equivalent deformation of 400%. The laminated composites were characterized both mechanically and microstructurally. Tensile tests revealed a four-fold increase in yield stress after 5 ARB passes. More importantly, an important reduction of the elastic modulus was detected. A Dillamore/Taylor coupled with a Goss texture measured by X-ray diffraction was found to be responsible for this reduction. Indirect and direct cell toxicity were carried out and confirmed that ARB processing has no detrimental effect in the biocompatibility of this materials. The results support this processing route as an attractive alternative for manufacturing biocompatible Nb-based implants.
