A brief introduction of the historical background of grain boundary engineering for structural
and functional polycrystalline materials is presented herewith. It has been emphasized that …

In 1984,'grain boundary design', later known as 'grain boundary engineering (GBE)', was
proposed. The central premise of GBE is that specific thermomechanical treatments, mainly …

In this work, we demonstrate a novel machining solution for controlling microstructures with
special grain boundaries and nanotwins in composites during laser powder bed fusion …

Abstract Twin boundaries (TBs) in Ni-based superalloys are vulnerable sites for failure in
demanding environments, and a current lack of mechanistic understanding hampers the …

The intergranular corrosion (IGC) resistance of 316L stainless steel (316L SS) produced by
selective laser melting (SLM) was investigated using microscopy analysis and …

A critical evaluation of recrystallization vs. strain induced boundary migration (SIBM) as the
mechanism responsible behind the grain boundary engineering (GBE) in alloy 617 is made …

The connectivity of high energy random boundaries was investigated on the basis of the
fractal analyses of grain boundary microstructures in SUS316L stainless steel, to prove the …

Additive manufacturing (AM) is a transformative approach to fabricating metal components in
the industry. However, it is challenging for fusion-based AM to fabricate metallic materials …

Alloys processed by laser powder-bed fusion show distinct microstructures composed of
dislocation cells, dispersed nanoparticles, and columnar grains. Upon post-build annealing …

Inherent thermal and mechanical instability of nanograined materials bottlenecks their
processing and technological applications. In addition to the traditional stabilization strategy …
