Multimodal data set for the investigation of the early stage of plasticity in a polycrystalline titanium sample

This dataset is the result of several experiments to study the early stage of plasticity in a polycrystalline sample of a commercially pure alpha phase grade 2 titanium (CP-Ti family). The study aimed to achieve three critical goals: first, the acquisition of a 3D representation of the microstructure; second, the conduction of in situ measurements capturing grain-scale plasticity dynamics during a controlled tensile test; and third, a rigorous comparison of these experimental observations against the predictions derived from a microstructure-sensitive crystal plasticity simulation. This simulation was conducted on a digital twin of the titanium sample, aiming to assess the predictive accuracy of the model at the local scale. The data set was assembled from the different sources using the Pymicro package.
