Stages of deformation curves and microstructures appearing in fracture zone of bioinert titanium and zirconium based alloys in coarse-grained and ultrafine-grained states
The stages of the deformation curves under quasistatic tension of Ti and Zr-1Nb alloys samples in the coarse-grained and ultrafine-grained states were studied using temperature curves obtained by IR thermography. The microstructures appearing in the fracture zone under deformation were investigated. New experimental data have been obtained indicating a significant influence of the ultrafine-grained state on the development of plastic deformation and fracture processes in Ti and Zr-1Nb alloys.
