Results of the European collaborative project “Product Uniformity Control“ to improve the inline sensing of mechanical properties and microstructure of automotive steels
Paper in proceedings, 2018
In this project, a multitude of strip steel samples from various stages of production have been collected from the four participating steel manufacturers. The samples have been characterised in various ways, namely on their (1) non-destructive measurement parameters using different techniques suited for inline evaluation, (2) fundamental ultrasonic and electromagnetic properties (wave speed, ultrasonic attenuation, magnetisation loops, coercive field), (3) tensile properties (stress-strain curves) and (4) microstructure (by optical micrographs and EBSD images). The correlations between these different characterisations will be addressed.
Besides the experimental characterisation, a strong accent has been on modelling activities: during the project, fundamental models have been developed to describe, starting from 2D and 3D microstructures, the ultrasonic and magnetic properties, which are next used as input to sensor models that predict the output of the inline measurement systems.
This contribution will present the recent results of both the experimental and the modelling work, and underline their mutual importance in the interpretation of the measured data for the benefit of inline characterisation of the mechanical properties complementary to traditional destructive tensile testing.
