| Abstract: | The influence of dynamic stresses on the progress of intercrystalline stress corrosion cracking Tests with steels sensitive and nonsensitive to stress corrosion cracking permit a seperation of the influences of static and dynamic stresses, respectively. The lightly alloyed steel resistant to stress corrosion does not lose its resistance even under dynamic stresses whilst the other steel, susceptible to stress without showing any recognisable correlation with the frequency. In the case of welded specimens, the service life is significantly reduced (mainly due to the overheating during welding). However, the resistance to dynamic stresses can be considerably by annealing at 800°C. |
