Abstract EN
Laser peening (LP) is an innovative surface enhancement process.
In which creates residual compressive stresses deep into part surfaces, to improve the resistance of metal.
It has particularly effective in compressor blades.
The compressive surface stresses resist the fatigue cracks initiation and propagation.
This paper outlines an experimental study on the effect of water laser peening (WLP) on mechanical and fatigue properties of 7349 Al-alloy.
The results show that the WLP can improve the mechanical properties and fatigue strength and life.
The WLP treatments gave increase in u 3.36% , in y by 1.4% and in HV by 5% compared to the as-received mechanical properties .While the endurance fatigue limit was increased by 4% compared to the dry endurance fatigue limit .
