  abstract = {The microstructure of a material defines many of its mechanical properties. Tracking the microstructure of parts during their manufacturing is needed to ensure the designed performance can be obtained, especially for additively manufactured parts. Measuring the microstructure non-destructively on real parts is challenging for optical techniques such as laser ultrasound, as the optically rough surface impacts the ability to generate and detect acoustic waves. Spatially resolved acoustic spectroscopy can be used to measure the microstructure, and this paper presents the capability on a range of surface finishes. We discuss how to describe 'roughness' and how this influences the measurements. We demonstrate that measurements can be made on surfaces with Ra up to 28 {$\mu$}m for a selection of roughness comparators. Velocity images on a range of real surface finishes, including machined, etched, and additively manufactured finishes in an as-deposited state, are presented. We conclude that the Ra is a poor descriptor for the ability to perform measurements as the correlation length of the roughness has a large impact on the ability to detected the surface waves. Despite this issue, a wide range of real industrially relevant surface conditions can be measured.},

Inconveniently, the same  materials’ properties which allow them to perform well in service render them difficult to process  via powder bed fusion. Current build systems are characterised by high defect rates and erratic  microstructure, leading to components with inferior mechanical properties. Given the high specific costs in  powder bed fusion manufacture there is a real and apparent need to minimise component scrappage due to  these defects. Here a method is proposed to make good the defects that will inevitably be  produced in current class laser processing of metallic powders. This study investigates the use of spatially resolved acoustic  spectroscopy (SRAS) scan data to inform repair strategies within a commercial selective laser melting  machine. Using the common aerospace nickel superalloys, Inconel 718 and CM247-LC, localised remelting was shown to consistently reduce the depth of defect. A 50 \% reduction in defect depth  was observed for both materials using different rework strategies. No appreciable variation was seen  with the single-shot strategy, due inaccurate realignment.},

The work presents microstructural texture imaging of powder-bed fusion components by a non-contact laser ultrasonic method, Spatially Resolved Acoustic Spectroscopy (SRAS). In short, this work demonstrates the ability to SRAS to detect and characterise meso-scale crystalline texture features. Probing samples manufactured by powder bed fusion, in the common nickel based aerospace superalloy Inconel 718, it has been shown the the primary crystalline orientation of can be inferred from the measured velocity, with good agreement with Electron Backscatter Diffraction. The studied sample was found to have a microstructure formation that bore a heavy resemblance to the chosen scanning pattern, with clear influence from the geometry through varying scan vector length and island-boundary scan strategy. this work forms part of a progression towards deployment of a SRAS system as an in-situ inspection solution for PBF.},

It works by measuring the velocity of surface acoustic waves (SAWs) via the acoustic spectrum.

−
As SRAS is a LUT technique is can be applied to a wide range of industrially relevant samples as a non-destructive evaluation technique. There are no size limitations on the samples that can be imaged and the surface preparation required is significantly more relaxed than many other techniques with the capability of operating on many as manufactured finishes. This permits the use of SRAS as an online inspection tool, for instance during additive or subtractive manufacturing, as a QA tool during manufacture or as an NDE/T tool in service.},
