EFFECT OF EQUAL-CHANNEL ANGULAR PRESSING ON CRACK RESISTANCE AND CORROSION DAMAGE OF ZIRCONIUM ALLOY Zr-2.5%Nb
- 1 The National University of Science and Technology “MISiS”, Moscow, Russia
Testing method for static crack resistance has been developed and applied for thin sheet (sample thickness ~ 1mm) samples of zirconium alloy Zr-2.5%Nb. Linear parameter of fracture mechanics – stress intensity factor Kc has been determined. Alloy Zr-2.5%Nb after ECAP was tested for corrosion resistance in the physiological Ringer’s solution for two years.
