Laser Non-Destructive Test to Find Aluminum Metal Physical Properties

Laser shock penning is a non-destructive laser testing used for analyzing material using lasers without causing damage, offering valuable insights into material properties; a recent experimental study focused on examining the al physical characteristics achieved by utilizing high-resolution optical microscopy and SEM images and investigated the effects of varying energy levels of Nd: Yag laser particularly analyzing the track effects the shock wave velocity was observed to depend on the surrounding medium influencing the ionization rates of the atoms involved notably Al subjected in water and ethanol exhibited a shock pressure of 4.5 GPa contrasting with the typical range of 0.46 to 3.2 GPa (in air, water, and ethanol environments) at a measuring laser intensity 11.4 GW/cm², This method was utilized for examining shock characteristics, encompassing particle speed, shock duration wavelength, energy strength, loudness level, and force, which were then used for assessing mechanical characteristics and juxtaposed with conventional methods. For example, tensile tests for stress-strain and Vickers hardness indicated that shocked Al in water and ethanol environments showed a closer correlation with tensile test results; in contrast, water demonstrated better alignment with Vickers hardness measurements. Additionally, there were discrepancies in elastic modulus values between tensile tests 28 GPa, and by laser shock, peening is 8.4 GPa, 4.9 GPa, and 4.7 GPa in air, water, and ethanol environments, respectively.
