... intensity thresholds for environmentally assisted cracking. Al-Si bronze was found to be susceptible to subcritical intergranular cracking in air and seawater, whereas Ni-Al bronze was unaffected. Both materials, however, are susceptible to cracking in the presence of ammonia, although the subcritical crack...

Failure mechanisms of fatigue fracture and environmentally assisted cracking were eliminated, because no evidence of SCC or fatigue fracture was observed; thus, the failure analysts focused on the possibility of overload failure. Further tests...
