Hi, I am Tina and I started my PhD in the fall of 2016. During my PhD, I will characterize the interface in joined materials, first and foremost joined aluminium and steel.
My background is from the nanotechnology study programme at NTNU. During my Master’s thesis work I used transmission electron microscopy (TEM) to study silicon carbide (SiC) from Saint-Gobain in Lillesand. With a transmission electron microscope, I can determine the crystal structure and composition of the investigated material. These characteristics determine the material’s mechanical properties and are thus important from an industrial perspective.
The joining of aluminium and steel
The research project that my PhD is a part of focuses on the development of multi-material products that combine desirable properties of the parent materials. First and foremost, the joining of aluminium and steel will be investigated, which is important where the combination of high strength and low weight is essential.
My role in this project is to use TEM to characterise the interface between aluminium and steel. Several different intermetallic compounds are found here, that influence the properties of the joint. I aim to get a thorough understanding of the interface and to link its characteristics at the microscopic scale back to the properties of the joint on the macroscopic scale.
Collaboration with other PhD candidates
I will collaborate closely with two other PhD candidates, Siri Marthe Arbo and Muhammad Zeeshan Khalid, who also work on this project. Siri Marthe works on the joining process itself and will provide me with samples for characterisation, while Zeeshan will use some of my data as input and starting parameters to perform simulations.
First months of my PhD
So far, I have been studying a sample made by SINTEF Chemistry and Materials, where aluminium and steel were joined using a cold metal transfer technique. For the next three years I will explore samples made from different aluminium and steel alloys and different joining techniques. I am excited to continue to improve on techniques within TEM and to get new and useful insights into these materials’ characteristics.
Thank you for reading and have a happy new year!
