Information × Registration Number 0211U007443, 0109U007597 , R & D reports Title Investigation of influence of production process parameters on formation of microstructure, mechanical properties and fracture appearance in specimens of Zr alloy tube produced by different variants. popup.stage_title Head Vakhrusheva Vira Sergijivna, Доктор технічних наук Registration Date 29-04-2011 Organization State Scientific Research Tube Institute popup.description2 In the course of this work, procedure of assessment of rupture viscosity in fuel casing tubes made of zirconium alloys has been developed. The system of image fixation during acqusition of data of crack development has been improved with the use of a videosystem and the technique of acquisition od data on cracks growth during testing. Test sensitivity has been improved for crack resistance assessment. Influence of scale values upon crack resistance indices has been assessed, crack resistance of Zr1Nb alloy specimens has been established with the use of various methods of data acquisition and comparison of the obtained results. Crack resistance of specimens prepared from hot-extruded and cold-worked tubes of ZrNb alloy in a wide size range made by a variety of process schedules has been studied, schedules of hot and cold working in making fuel casing tubes in industrial conditions have been corrected.
