The influence of ultrasonic impact peening (UIP) on the mechanical properties and fatigue life of the AA1100 alloy

The effects of ultrasonic impact peening (UIP) on the mechanical properties and fatigue strength AA1100 alloy were compared to those untreated alloy. UIP technic is widely used in a variety applications increase hardness, tensile strength, surface characteristics, life metals. Due plastic deformation layer, process generated compressive residual stresses metal's upper layers. Extensive investigations carried out order determine significant effect characteristics metal. According results experiment, percentage ultimate (UTS), yield stress, hardness 8 %, 7.05 9 respectively. A substantial improvement was seen as result this treatment when samples. demonstrated that reliable approach for generating alloys, which may have favourable influence behaviour alloys.
