Description

Research complex method, which includes: methods for determining the mechanical characteristics under various schemes of deformation, methods for determining the characteristics of fracture toughness and hardness, structural methods of investigation, and acoustic emissions was developed. The various types samples for investigation , which were made directly from fuel tubes were selected. The mechanical properties and acoustic parameters of tensile alloy ring samples Zr1% Nb, made of fuel tubes after various chemical and thermal treatments and various coatings was defined. For samples with fuel tube after oxidation and coating established the relationship between changes in mechanical properties in tension with the peculiarities of their acoustic spectra. The mechanical properties and acoustic spectra of fuel tubes from zirconium after modifying their surface by various means was obtained. The database which describe the characteristics for fuel tubes of zirconium alloy Zr1% Nb after surface modification in various ways was obtained.
