Incoherent tilt grain boundaries stabilized by stacking faults and solute-cluster segregation: a case-study of an Mg-Gd alloy

Despite their wide presence in hcp metals, incoherent tilt grain boundaries (ITGBs) are rarely studied.In this work, first-principles calculations were combined with atomic-resolution HAADF-STEM analyses to investigate the structure and formation of one NUTRA VEGE EXTRA STRENGTH 1000MG special type ITGB in an Mg-Gd alloy featured with a unique Gd-r
