DOI: 10.1016/j.matlet.2020.128802
Abstract: Abstract Grain boundary triple junctions (TJs) are 1-dimensional microstructural elements on their own with specific thermodynamic and kinetic properties, which are different from the connecting boundaries. Our study compares the segregation and precipitation evolution near… read more here.
