| Abstract Scope |
In the last decades, the automotive industry has increased the usage of cast aluminum. To enhance the quality of their products, foundries must focus on minimizing casting entrainment defects during the production process. Defects can be divided into visible and hidden damage to the structural component. The visible defects, such as pores and bubbles, have been the primary focus of quality assurance in foundries. Yet, recent evidence shows that most of the damage given to liquid metals remain hidden, only to reduce tensile properties and fatigue performance in service.
This work presents ways to identify the hidden damage in cast aluminium using in-situ cyclic testing in a scanning electron microscope equipped with a Focused Ion Beam. Moreover, applying Digital Image Correlation to cyclic tests and tensile tests showed the hidden damage in an early stage.
The combined results show that the hidden damage impacts the mechanical properties significantly. |
