In present work a numerical and experimental investigation into laser assisted foaming inside a hollow profile was conducted. The aim is to examine the feasibility of the laser foaming through laser irradiation of a steel hollow profile, which contains the aluminium foamable precursor. Experimental activity demonstrates that three process parameters have to be taken into account: interaction time, laser energy density and total amount of beam energy delivered towards the work-piece. Numerical simulations allows the qualitative evaluation of the temperature field inside the solid precursor with the purpose to better understand the process parameters modification effect onto the process.

Abstract

In present work a numerical and experimental investigation into laser assisted foaming inside a hollow profile was conducted. The aim is to examine the feasibility of the laser foaming through laser irradiation of a steel hollow profile, which contains the aluminium foamable precursor. Experimental activity demonstrates that three process parameters have to be taken into account: interaction time, laser energy density and total amount of beam energy delivered towards the work-piece. Numerical simulations allows the qualitative evaluation of the temperature field inside the solid precursor with the purpose to better understand the process parameters modification effect onto the process.
