I broke this piece of pure vanadium by putting it through a rolling machine. The fracture surface consists of many harsh, right angles. It's likely a form of brittle fracture but unlike anything I've ever seen.
I have to occasionally etch tantalum to evaluate grain structure, but I often times find the etchant doesn't fully reveal the grain boundaries. Perhaps using a color etchant as well is worthwhile....

What I did (unpublished yet) is extract several (e.g. 16) mask features within Mask R-CNN from multiple images, construct a distance metric to compare them to predict the image class. Each set of...

I've only come across models that were trained and evaluated on one of these data. I don't see why it would be a problem to do both, as there are many similar features.

When we look at the binding energy spectrum of an element, we see peaks originating from various atomic orbitals. If the atom changes in chemical state, the peak positions shift around. For...

I must measure the oxidation resistance of several cobalt-based super alloys. Since time is short, it might be a good idea to leave them in a tube furnace filled with pure oxygen to accelerate the...

Often times, a pure metal is described as isotropic because the mechanical properties do not vary with direction. However, I recently learned that Young's modulus changes with direction according...

Cross-slip, twinning and fracture are major deformation modes adopted by loaded materials. It appears sound that these apparently different deformation mechanisms can be analysed on the equal manner!
