ABSTRACT A quasicrystalline approximate monoclinic phase η-Al5(Mn,Cr) with a plate-like or rod-like morphology in AA5083 aluminium alloy was investigated using transmission electron microscopy. Several types of orientation relationships (ORs) between the η-Al5(Mn,Cr) phase and the α-Al matrix were observed and these ORs could be correlated with a rotation operation around the axis with an angle that is an integer times 18.5°. These multiple ORs were interpreted by utilizing an invariant deformation element model – a simplified version of three-dimensional invariant line strain analysis.

ABSTRACT The objective of this technical note is to illustrate twofold. The first issue is devoted to the ability of the recently developed smoothing gradient-enhanced damage model (SGDM), which is associated with the modified von Mises equivalent strain in modelling mixed-mode fracture problems, in particular the common Nooru–Mohamed's test. We show that the developed approach works pretty well for this test, yielding appropriate structural damage response and crack paths for all three specimen sizes, i.e. and . The second issue is, in a similar manner, to discuss the less accuracy of another damage model, the localising gradient damage scheme recently studied by Shedbale et al. Int. J. Mech Sci 2021, 199:106410, in reproducing crack paths and structural responses for the same mixed-mode problem.

ABSTRACT Our studies formulate a classical theory to study the influence of in-plane electric field on electron-impurity scattering process and magnetotransport in a two-dimensional space, in the presence of a strong out-of-plane magnetic field. Our studies connect classical scattering and quantum Landau Level broadening, as will be reviewed in this report. We derived an electric current formula in agreement with the current derived from the Drude theory under a strong magnetic field. Our electric current formula is derived microscopically from the migration of the guiding centres at strong magnetic field regime . The electron-impurity scattering under electromagnetic field not only shifts the guiding centre coordinates X and Y, but also changes cyclotron radius R. The change of cyclotron radius R compensates the change of the electric potential energy during the scattering process. The broadening of cyclotron radius is a classical manifestation of Landau Levels broadening. Our conductivity derived from our current formula in the linear response regime results in the same as the current derived from Kubo current fluctuation theory, providing a special case of the fluctuation-dissipation theorem.

ABSTRACT To elucidate the complex mechanism of solid-solution strengthening in high-entropy alloys (HEAs), it is necessary to determine the effective atomic radii of the constituent elements that are the sources of lattice strain. In the present study, the effective atomic radii of the constituent elements in CrMnFeCoNi HEA that are the basis of the atomic displacements, are evaluated from lattice parameters experimentally determined via θ–2θ X-ray diffraction measurements. The order of the evaluated atomic radii in the present study is different from that of the atomic radii determined via ab-initio calculations in previous studies. The results of the ab-initio calculations indicate a correlation between the yield stress of and the average atomic displacement in the HEA. However, no definite correlation is confirmed by the experimental results in the present study.

ABSTRACT The lack of high-strength Al alloys that can be processed by laser powder bed fusion (LPBF) without formation of cracks is considered as one of the main issues for a wider diffusion of this technology in many fields. In this study, the effect of Cu content on the hot-crack resistance of Al-Cu-Mg alloys produced by LPBF was investigated. Powder batches with different compositions were produced by mixing pre-alloyed gas-atomised 2024 alloy powder with increasing amounts (4, 6, 8, 10, and 12 wt.%) of Cu particles and then processed by LPBF. Thermodynamic simulation and microstructure investigations showed that the addition of Cu promotes the formation of abundant eutectic phase mixture, refines the grain structure and reduces the solidification temperature range, thus decreasing the solidification cracking susceptibility of the material. Samples produced with more than 10 wt.% of Cu featured relative density higher than 99.5% and no solidification cracks.

ABSTRACT The tension–torsion properties and deformation microstructure of near β titanium alloy after various heat treatment have been investigated by transmission electron microscopy (TEM). The samples after aging treatment at 500°C for 8 h possesses obviously higher strength than those samples undergoing other different treatment on account of thin α” plates distributing uniformly in the β grains. Interestingly, precipitation of α″-martensite in α plates were observed for the first time under tension–torsion deformation. The abnormal precipitation behaviour was attributed mainly to the large tensile-shear stress.

ABSTRACT In the present study, the structural evolution of the precipitates in Mg-Gd-Y-Zr alloy is investigated by means of high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM). The linearly aligned morphology of phases connected by bridging phase in one of the three equivalent crystal directions of is formed from defect-free randomly distributed phases. Considering the significant strengthening effect of precipitates, a novel perspective of investigating the induced strain field measured by geometric phase analysis (GPA) is conducted. The reducing value of the strain field accounts for a slight decrease in hardness after peak-ageing. Merging and rearrangement of precipitates are found to release the strain field.

ABSTRACT The role of damage in the degradation of tensile properties related to a stress-induced martensite transformation in a hydrogen-charged Ni–Ti superelastic alloy has been investigated. By damage, we mean vacancy clusters and dislocation structures induced in advance by a dynamic interplay between hydrogen and the martensite transformation. To homogenise the hydrogen concentration, the specimen was aged at room temperature after charging with a small amount of hydrogen (approximately 30 mass ppm). In this case, no fracture occurs within 2000 cycles during a cyclic tensile deformation test in the stress plateau region generated by stress-induced martensite and reverse transformations. With this hydrogen concentration, cyclic interplay between hydrogen and the martensite transformation scarcely leads to the degradation of tensile properties. Nevertheless, following cyclic martensite transformations before aging that induces pre-damage, fracture occurs after around 1000 cycles under a cyclic tensile deformation test despite the hydrogen concentration being the same. The present results clearly indicate that pre-damage induced by hydrogen affects the subsequent transformations, thereby causing the self-multiplication of damage, which degrades the tensile properties.

ABSTRACT The elastic field of an angular dislocation determined by Yoffe ([The angular dislocation. Phil. Mag. 5(50) (1960), pp. 161–175]) using isotropic elasticity is a convenient tool for modelling defects in very different materials such as crystalline media or the Earth’s crust deformed by internal shifts. We show that the anisotropy of the medium can be introduced in two ways to solve the same problem, one using an integral formalism and the other the Green’s tensor attached to a homogeneous medium. β’ CuZn brass, which has a strong elastic anisotropy, is treated with the two methods, and the results are compared.

ABSTRACT A strong temperature-dependent effect in the range from 25°C to 700°C in the nanomechanical behaviour has been found in a single-crystal nickel-base superalloy. The hardness of this alloy gradually increases from 25°C to 400°C and then rapidly decreases, in contrast to the peak tensile yield strength which occurs at around 700°C. The nanomechanical response is strongly dependent on the indentation load over a wide range of temperature, which is rationalised by its unique γ/γ’ dual-phase microstructure. The experimental measurements show that the hardness is position-sensitive owing to its unique solidified dendrite microstructure when the indentation marks span 640 μm.
