DOI: 10.1016/j.actamat.2018.10.002
Abstract: Abstract Tungsten is notoriously brittle metal at room temperature. Furthermore, contrary to most metals, plastic deformation increases ductility and recrystallization decreases ductility of tungsten. The fundamentals that govern this behavior have challenged academia and industry… read more here.

DOI: 10.1016/j.micron.2020.102825
Abstract: For nanometer-scaled materials, grain boundary behaviors, such as grain coalescence and grain boundary migration, contribute significantly to the plasticity of materials. While mechanically driven grain growth has been observed in nanometer-scaled metals, its underlying mechanisms… read more here.

DOI: 10.3390/membranes12060617
Abstract: A higher density of large-angle grain boundaries in palladium membranes promotes hydrogen diffusion whereas small-angle grain boundaries suppress it. In this paper, the microstructure formation in 10 µm thick palladium membranes is tuned to achieve… read more here.
