Additive manufacturing (AM) is a cutting-edge technique that builds parts by adding layers
from a digital design and depositing materials selectively where required. AM is vital in …

A superalloy is a metallic alloy which can be based on iron, cobalt or nickel etc. Nickel
based superalloy is best suited for aeroengine applications. In addition to aero engine …

Abstract Inconel 718 (IN718) superalloy is a well-established material for the application of
aircraft engine and power generator due to its excellent performance at high temperatures …

Although intermetallics are attractive for their high strength, many of them are often brittle at
room temperature, thereby severely limiting their potential as structural materials. Here, we …

We describe an approach that enables the activation of two distinct nanocrystalline stability
mechanisms in the same Ni (P) alloy by controlling the annealing temperature and chemical …

In this work, the microstructure and mechanical properties at both room temperature (RT)
and 250° C of an as-extruded Mg-Ca-Mn based alloy have been systematically investigated …

Targeted doping of grain boundaries is widely pursued as a pathway for combating thermal
instabilities in nanocrystalline metals. However, certain dopants predicted to produce grain …

A primary shortcoming of nanocrystalline materials is that they tend to coarsen at elevated
temperatures, which limits their practical application. Nowadays, it is crucial to develop a …

Gradient structured metals have shown unique mechanical properties, such as high strength
and good ductility. In this study, a gradient TWIP steel was fabricated by surface mechanical …

Grain boundary movement is closely related to plastic deformation of materials. In our
contribution, C atoms are introduced into the grain boundary and a highly stable C chain …
