| Popis: | Ti – Zr-based alloys with a high zirconium content prepared by vacuum-arc remelting with nonconsumable tungsten electrode are studied. The optimum number of remelting operations and melting conditions in order to achieve a highly uniform distribution of components and low content of impurities in the alloy are determined. Optimum thermomechanical treatment (cold rolling) and post-deformation annealing regimes are proposed. X-ray studies are conducted at room temperature and after thorough cooling in order to determine the crystallographic resource of alloy reversible deformability. Alloy susceptibility towards superelastic behavior at room temperature, cyclic endurance and its dependence on annealing atmosphere are evaluated in the course of tension-compression mechanical tests. |
