Delayed hydride cracking in zirconium alloys in pressure tube nuclear reactors, LAEA-TECDOC-1410(2004). [Pg.470]

The environments, along with the cracking modes of zirconium and titanium, are given in Table 4.88. It is obvious from the table that zirconium alloys are susceptible to stress-corrosion cracking in a variety of environments. It is necessary to subject the weld to heat treatment in order to lower the stress in the weld. The most serious problem encountered in the nuclear applications is delayed hydride cracking in addition to stress-corrosion cracking, particularly in Zr-2.5% Nb alloy. [Pg.291]

A possible mechanism for TGSCC of Mg alloys is delayed hydride cracking (DHC) [5,9,99,113,114,118]. Previous workers have proposed various models relevant to DHC in hydride-forming metals, particnlarly Zr alloys. Liu [176] and van Leeuwen [177] derived analytical solntions for the steady state and transient distribution, respectively, of lattice H ahead of a sharp crack however, these models did not include hydride precipitation. Dutton et al. [178] derived an expression for the rate of hydride growth in... [Pg.343]
