Abstract [en]

Automotive industries have been putting extensive effort into producing engine materials considering resistance and weight of the engine material. This material should withstand higher combustion pressure and in the meantime should be lighter. Compacted Graphite Iron (CGI) is a material that could allow achieving these design requirements. But the variation of the CGI material and mechanical properties are very high within the given specifications. The thesis is focused on classifying CGI according to its material and mechanical properties. Impact Acoustic Testing method is a Non Destructive Testing method which is fast and might be able to classify the CGI materials based on its properties. The method can measure the structural response of a part. Its volumetric approach tests the whole part providing objective and quantitative results. The result was that the method could able to distinguish between gray iron and CGI, and could distinguish partly among CGI.

Keywords: Non Destructive Testing, Impact Acoustic Testing, Compacted Graphite Iron
