Abstract Scope |
Additive Manufacturing (AM) has the ability to produce parts of high strength due to the rapid cooling rates associated with the process. As a result, the ductility will naturally suffer as a consequence. The material of interest is a popular aluminum alloy (AlSi10Mg) that contains 10% silicon and is widely used in the space industry for its good mechanical properties and light weight. This alloy will be studied to observe the impact of applying heat treatments on the damage evolution and mechanical properties of AlSi10Mg produced through additive manufacturing. Techniques such as in-situ tensile testing via x-ray computed tomography and in-situ tensile testing via scanning electron microscopy (SEM) coupled with micro-digital image correlation (μ-DIC) will help connect microstructural features to areas of high strain localization and void growth, such that a process-structure-property relationship can be established. |
