What is it about?
Traditionally formability tests are done on large specimens at larger length scales leading to more material wastage. Also, no information is available on the microstructural length scale from these tests. We overcome these issues by building a setup capable of performing the same tests inside a scanning electron microscope.

Why is it important?
The experimental setup proposed in this work is the first of its kind. It allows the user to measure the formability of materials under various strain paths accompanied by strain measurement at the microscopic length scale. This enables the correlation between macroscopic and microscopic formability parameters, useful especially for small components.
Perspectives
Working on and writing about this research has provided immense joy to me since this was possibly the most challenging part of my doctoral research. Despite multiple roadblocks, I am happy to say that I was able to overcome them.
