METHOD OF THERMIC WORKING ZIRCONIUM ALLOYS Russian patent published in 1995 - IPC

Abstract SU 1767924 A1

FIELD: alloy working. SUBSTANCE: articles were subjected for heating up to 920-950 C at the rate 100 C/s (not less), kept at this temperature for 10-15 s, cooled up to the room temperature at the rate 450-1200 C/s at the range of temperature 920-500 C followed by annealing at 580-540 C for 24-100 h, respectively. This working improves creeping and corrosion resistance due to making quasi-isotropic fine-grained structure. EFFECT: improved method of working. 4 tbl, 2 dwg
