Abstract Nickel (Ni) is a magnetic transition metal with two allotropic phases, stable face-centered cubic (FCC) and metastable hexagonal close-packed (HCP), widely used in structural applications. Magnetism affects many mechanical and defect propert

The superior mechanical strength of Inconel 718 and similar Nb containing alloys mainly results from the ordered γ″-Ni3Nb precipitates. By employing first-principles calculations, we comprehensively investigate the effects of alloying elements (i.

A polycrystalline material is an aggregate of crystallites with different lattice orientations. The crystallites, i.e., grains, can undergo nearly-rigid-body rotation. Such rotations have been widely observed in polycrystalline materials during grain

In Ni-based superalloys, it is usually found that borides can strengthen the grain boundaries, thereby resulting in an increase in mechanical strength and high-temperature creep properties....

Grain boundaries (GBs) have profound effects on the dislocation motion in materials so as to cause crack nucleation. However, the experimental observation on how the misorientation of twist GBs affects the crack nucleation is scarce. In this paper, w

A theoretical investigation of Cu segregation effect on phase constitution, magnetic, and mechanical properties of FeCoNi(CumAl)x high-entropy alloys is presented. Results show that the homogenous FeCoNi(Cu1.0Al)x only exists as a single face-centere

Although Cr-rich (Cr, M)23C6 (M = Fe, Mo) carbides as ineluctable precipitates dramatically affect the mechanical performances of advanced materials such as refractory steels and superalloys, their high-temperature material properties are difficult t
