Abstract
The presentation of data obtained from stress‐corrosion experiments, in which the effect of stress on the time‐to‐failure is determined, is discussed.Methods are suggested by which the susceptibility to stress‐corrosion of materials may be expressed on a comparative basis. The results given in Part I on the stress‐corrosion of aluminium—7%‐magnesium and aluminium‐5%‐magnesium alloys are used to illustrate the methods.
