The unsupervised learning technique, locally linear embedding (LLE), is applied to the analysis of X-ray diffraction data measured in-situ during the uniaxial plastic deformation of an additively manufactured nickel-based superalloy. With the aid of

It is well understood that twinning during deformation plays an important role in deformation of Mg and its alloys [1, 2, 3, 4, 5, 6, 7, 8]. In hexagonal close packed (HCP) Mg alloys, the dominant deformation mode at room temperature is slip on the b
