Abstract

Specimens of dispersed-oxide-strengthened lead containing 4.5 wt % oxide were fatigued at room temperature (∼ 0.5 T m where T m is the melting point in degrees K) in air and in vacuum (< 2×10−4 torr). Metallography of the damage during fatigue and after fatigue fracture showed that the improved fatigue resistance of dispersed-oxide-strengthened lead (DS lead) over that of pure lead was due mainly to the mechanical strengthening effects of the dispersed oxide rather than an increase in the resistance to atmospheric corrosion fatigue. The ratio of the fatigue life of DS lead in vacuum to that in air was ∼ 8.5 at a strain of ± 0.145%. In specimens fatigued in air, failure occurred at grain boundaries and in those fatigued in vacuum it occurred by a mixture of intercrystalline and transcrystalline modes.
