Solid solution strengthening is the major mechanism that accounts for high strength of single-phase body-centered cubic (BCC) refractory high-entropy alloys (RHEAs). Local lattice distortion (LLD), often regarded as one core effects HEAs, generally believed to be deterministic in solid RHEAs since loosely packed BCC crystal structure can accommodate significant LLD. To systematically investigate effect LLD on strengthening, present study deliberately introduced different degrees...
Myeloid-derived suppressor cells (MDSCs), a population derived from immature myeloid progenitors, are present in the tumors of patients and highly protumorigenic. However, molecular mechanisms regulating MDSC infiltration remain unclear. Neddylation pathway is overactivated multiple cancers has significant role tumor progression. We established subcutaneous transplantation model Lewis lung cancer mice showed that inactivation neddylation inhibits impairs growth. A high expression level...
ZrO2 is an attractive host matrix for luminescence material because of its excellent physical properties, such as low phonon energy and wide band gap. In this work, the highly transparent Tm2O3 Yb2O3 co-doped yttria stabilized zirconia (YSZ) (abbreviated Yb/Tm: YSZ) single crystals were grown by optical floating zone method. The YSZ samples in cubic phase at room temperature when Yb3+ Tm3+ replaced Y3+. influence co-doping on up-conversion properties was systematically studied. A total 0.5...
Metallic glasses are topologically disordered down to the atomic scales. As a result, during mechanical deformation there random displacements which necessarily lead volume change. Although dilatation has been observed, its contribution and pressure sensitivity in yielding fracture strengths remains controversial; since is thermodynamic conjugate variable hydrostatic pressure, change must be accompanied by certain degrees of sensitivity. However, among available measurements, negligible...
Abstract By means of ab initio calculations, a unified framework is presented to investigate the effect internal displacement on linear and nonlinear elasticity single diamond crystals. The calculated elastic constants, strain tensor in crystals are compatible with available experimental data other theoretical calculations. complete set second-, third- fourth-order constants not only offer better insight into anisotropic behaviors, but also shows us basic mechanical response diamond. This...
Theoretical strength plays a pivotal role in gauging the maximum stress and inferring structural defects crystalline materials. However, its very existence expected prediction of possible amorphous solids remain elusive. Here, by using finite deformation theory, we obtain theoretical strengths for several bulk metallic glasses under pure shear loading. The obtained are only times larger than experimental yield stresses; contrast, they three or four orders magnitude higher This striking...
This paper investigates the ultra-fast heating process of Cu-Pd bimetallic nanoparticles from an atomic-scale perspective, which is essential for laser manufacturing processes, such as cladding and selective melting. The behavior high surface ratio during these processes strongly influenced by their properties process, governed atomic dynamics. Previous studies have mainly focused on combination in pure metallic under slow or isothermal heating, but this work demonstrates that dynamic...
5083 aluminum alloy (AA5083) is prone to produce pores and undercut defects during laser welding because of violent fluctuations Mg elements burning in a molten pool, which seriously affected the tensile properties welds. In this paper, process with filler wire was used improve weld properties, through experiments finite element simulation (FES), effects wires (ER4047, 5356, 5087) on joint failure behavior were studied. The FES results are very consistent digital image correlation (DIC)...
<title>Abstract</title> Multi-laser powder layer bed fusion (M-LPBF) has wide application prospects in aerospace, biomedical and industrial fields, dramatially improving the efficency of LPBF. However, spatter still weakens quality built part. With different scanning strategies, distributed various printing locations may result compromised processing. By far, existing models, spatters are assumed as fixed particle size or multiple injection angles, which do not adapt well to from melt pool....
