Titanium alloys, widely used in the aerospace, automotive and energy sectors, require
complex casting and thermomechanical processing to achieve the high strengths required …

Additive manufacturing, also known as 3D printing, overcomes many design and
manufacturing constraints to allow almost direct production of metals into complicated …

Additive manufacturing, often known as three-dimensional (3D) printing, is a process in
which a part is built layer-by-layer and is a promising approach for creating components …

Due to the low thermal stability of crystallographic boundaries, the grain boundary
engineering (GBE) manifests some limits to the fineness and types of microstructures …

Additive manufacturing (AM) creates digitally designed parts by successive addition of
material. However, owing to intrinsic thermal cycling, metallic parts produced by AM almost …

Nanostructured metals are usually strong because the ultrahigh density of internal
boundaries restricts the mean free path of dislocations. Usually, they are also more brittle …

The coarse prior-β grain structure in titanium alloys produced by additive manufacturing is
associated to mechanical anisotropy and limited fatigue life. Here we report a novel …

Metal-based additive manufacturing (AM) permits layer-by-layer fabrication of near net-
shaped metallic components with complex geometries not achievable using the design …

Lightweighting of automobiles by use of novel low-cost, high strength-to-weight ratio
structural materials can reduce the consumption of fossil fuels and in turn CO2 emission …

Preventing columnar grain formation during additive manufacturing has become a
significant challenge. Columnar grains are generally regarded as unfavourable as their …
