It has been proposed that a primary water stress corrosion cracking (PWSCC) in pressurized water reactor (PWR) is governed by a lattice contraction due to a short range ordering reaction in Alloy 600. This leads researcher to think that the kinetics of lattice contraction may control a susceptibility of PWSCC in Alloy 600. A lattice variation with ordering treatment at 400 <sup>o</sup>C was systematically investigated using high resolution neutron diffraction(HRPD) in high temperature mill anneal (HTMA), low temperature mill anneal (LTMA), and sensitized (SEN) Alloy 600. The results showed that ordering treatment caused an isotropic lattice contraction due to short range ordering (SRO) reaction. The lattice contractions of (111) plane are saturated to be 0.04% in 4 to 1500 hours at 400 <sup>o</sup>C according to prior treatment condition. The lattice contraction in the magnitude of 0.03% of (111) plane in LTMA Alloy 600 is faster by 8 times and 66 times than that of SEN and HTMA, respectively. This fact may explain why the LTMA is most susceptible to PWSCC through of kinetics of lattice contraction in Alloy 600. Thus, it is possible to conclude that the susceptibility of Alloy 600 to PWSCC is governed by the kinetics of (111) lattice contraction.

The kinetics of short-range order (SRO) formation was investigated in the alloy Au25Ag25Pd50by using the residual electrical resistometry. The resistivity was found to increase with the formation of SRO. The resistivity values varied linearly with respect to the inverse of temperature, characterizing the different states of SRO. The analysis of isothermal experiments obeying the fundamental laws showed that the SRO kinetics followed the two-exponentials law. The characteristic time constants for the SRO formation corresponding to various annealing temperatures in the isothermal annealing process and the activation enthalpies were determined with high accuracy. The time constants for the SRO formation and destruction were different, implying that the reaction paths in these processes are different. Further, the crossover experiments confirmed the existence of two-exponential kinetics and the variation of the time constants.
