An ultrasonic technique is one means of doing this ...
Additive manufacturing (AM) of metals, also known as metal 3D printing, typically leads to the formation of columnar grain structures along the build direction in most as-built metals and alloys. These long columnar grains can cause property anisotropy, which is usually detrimental to component qua...

A NUMBER of years ago, Wood1 suggested that the circumferential spreading of the sharp X-ray diffraction spots from annealed grains into continuous arcs along the Debye circle on deformation could be best accounted for by supposing that the grains break down into a number of fragments oriented at...

The correlation between the structure and zero-temperature energy of symmetrical tilt grain boundaries (STGBs) in b.c.c. metals is investigated using a many-body potential of the Finnis-Sinclair type for Mo and Johnson's pair potential spline-fitted for α-Fe. As in free surfaces, the misor...
of nanostructured metals by modifying the architectures of their interfaces. The amount, structure and distribution of several types of interfaces, such as high- and low-angle grain boundaries and twin boundaries, are discussed. I survey several examples of materials with nanotwinned and nanolaminated ...
