Abstract:  
A study was made of the effects of multiple shot-peening and Cd plating operations on high-strength AISI 4340 steel used in aircraft landing-gear applications. No detrimental effects were observed on surface microstructure and tensile properties or on fatigue and unnotched stress corrosion resistance in high-humidity air. An apparent degradation in stress corrosion life of fatigue precracked specimens was observed after four and five peening and plating operations.
