Use of Second Harmonic Generation for Determination of Aluminum Sensitization
Abstract
Funds are provided to analyze the correlation between Second Harmonic Generation (SHG) and Degree of Sensitization in marine grade aluminum alloys. SHG is a second order, nonlinear optical technique, that measures a laser beam interaction with a surface, has inherent sensitivity to surfaces and interfaces. In the proposed work, the PI will evaluate the feasibility of the SHG for the detection of the beta phase using various sensitized aluminum 5000 series alloys provided by NSWCCD by investigating the local structure, chemistry and symmetry of those alloys. The proposed work is based on the previous results that obtained using SHG to determine mechanical deformation, chemical modification, and other stress can change the surface morphology or texture of the metallic materials.
