ABSTRACT Parameters of the Ashcroft and Heine–Abarenkov model potential have been computed for face-centred cubic (fcc) actinium (Ac) crystal. The calculation uses the pseudopotential technique with nine different exchange and correlation functions and an empirical relation based on other experimental parameters, namely, the melting temperature and the cohesive energy. The complete set of values for this parameter will be used for future calculations of self-diffusion and impurity diffusion via a vacancy mechanism or via other types of defects.

ABSTRACT The ZrB2–SiC–LaB6 composite prepared by spark plasma sintering with B4C and C as additives was isothermally exposed in air at 1500°C for 24 h and the evolved oxide scale examined by scanning and transmission electron microscopy. It was found that a glassy borosilicate (BSG) layer with a thin film of La2Si2O7 had formed on the outermost surface of oxide scale, contributing to protection against oxidation. The detailed investigation of the cross-section of the oxide scale has revealed the formation of a layered microstructure formed by growth involving partial crystallisation of BSG forming ZrSiO4 along with re-precipitation of La2Si2O7 and ZrO2 after prior dissolution of La2O3 and ZrO2 in the glassy matrix.

ABSTRACT In order to prepare high-performance tungsten alloys, surface modification of tungsten nanopowders prepared by a wet chemical method was carried out by acid pickling at room temperature. The low-temperature sintering characteristics of tungsten nanpowders before and after pickling was compared and analysed. The surface modification was carried out by pickling with a solution of hydrofluoric acid, concentrated nitric acid and ammonium fluoride at room temperature. After this surface treatment, uniformly distributed step-shaped defects formed on the surface of the tungsten nanopowders. After low-temperature sintering, the grain size of the tungsten alloy corresponding to the surface-modified powder precursor was reduced by 20% compared to the alloy using untreated powder as precursor. In addition, the step-shaped defects also increase the sintering activity of the pickled tungsten powder and promote its sintering densification, making the final density of pure tungsten sintered at 1600°C as high as 96.7%, and its hardness greatly increased to 521 HV0.2. The results show that room-temperature pickling and subsequent low-temperature sintering is a promising method for preparing high-performance nanotungsten alloys.

ABSTRACT Silicon carbide is an important material with applications in numerous domains, but for which our knowledge of basic properties like elastic constants is surprisingly limited. Although several density functional theory calculations have been reported, those are usually not accurate enough, with a sizeable dispersion of published values. A heuristic method is proposed here, allowing for largely reducing the uncertainty. It is based on the use of a weighted average of errors for two reference materials, Si and C. It is demonstrated that this method is effective for physical properties like the lattice parameter and the bulk modulus. It is then used for determining the full sets of elastic constants for the 3C, 2H, 4H, and 6H silicon carbide polytypes.

ABSTRACT We employ first-principles calculations to examine the role of oxidation on the thermal expansion behaviour of a refractory multicomponent alloy. Our results reveal that the linear expansion and the coefficient of volumetric expansion over a range of temperatures have higher values for the oxidised alloy than the pure material. The enhanced expansion for the oxidised alloy is attributed to significant changes in the lattice parameter of the alloy upon surface oxidation. During oxidation, the diffusion of oxygen atoms to the subsurface layer of the alloy after complete surface coverage produces a displacement of the constituent elements that form metal oxides. This depletion creates vacancy sites in the lattice for enabling enhanced expansivity in the oxidised structure relative to the pure refractory alloy.

ABSTRACT The evolution of microstructure and the variation of strain field induced by precipitation in Al–Si–Mg–Cu alloy with high copper content during early ageing is characterised by high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) and geometric phase analysis (GPA) calculations. The basic building blocks for GP zones and step-shaped edges around subsequent precipitation are characterised. Incorporation of solute atoms, namely Si, Mg and Cu, accounts for the expansion of GP zones with core–shell structure and further precipitation transformation. The induced strain field rises as the ageing time increases and structural transformation proceeds, which results in a hardening of the sample.

ABSTRACT In the present work, we adopt a computational approach to study the evolution of microstructure during solidification of a Ti-Fe-Co-Ni-Cu multi-component alloy system by regarding it as a Ti-(Cu, Ni)-(Fe, Co) pseudo-ternary-alloy system. The as-cast alloy has a eutectic morphology with lamellar structure between (Cu)SS and a Laves phase. A Kim-Kim-Suzuki (KKS) phase-field model for eutectic solidification is implemented for this multi-component alloy system using a MOOSE finite element framework. The model is implemented for different scenarios, which include the simulation of microstructures at eutectic temperature and for small degrees of undercoolings (ΔT = 2°C, 5°C, 8°C, 10°C). Analysis of the microstructure evolution reveals that an increase in undercooling leads to a higher growth velocity and a larger volume fraction of solid phases. GRAPHICAL ABSTRACT

ABSTRACT The specific heat capacity of half-Heusler ScNiSb and TmNiSb compounds have been calculated using a simple approximation in the temperature range 0–298 K. The results obtained for the specific heat capacities are in good agreement with the experimental data in the literature. The Debye temperatures were derived by fitting the analytical expression obtained in this study to experimental data. The Debye temperatures and the Sommerfeld coefficients resulting from the fitting are 355.95 K and 7.19 mJ/mol.K for ScNiSb, and 234.5 K and 14.92 mJ/mol.K for TmNiSb.

ABSTRACT In situ observation of a phase transformation during annealing of Si containing diamond-cubic (dc) and metastable phases has been performed using synchrotron X-ray diffraction. Metastable body-centred-cubic (bc8) and rhombohedral (r8) phases were formed by high-pressure torsion. These metastable phases gradually disappeared when increasing the annealing temperature to ∼ 180°C while another metastable phase having a hexagonal diamond (hd) structure appeared at ∼ 190°C. High-resolution transmission microscopy analysis revealed that hd and dc grains were present after annealing at 200°C. The results indicate that a phase transformation, mainly from bc8 to hd, occurred during annealing.

ABSTRACT The present work quantifies the contribution of constituting phases to the strain hardening in a medium-Mn steel during Lüders deformation. The strain hardening of the ferrite matrix (∼ 46.1 MPa) is much lower than that of the austenite phase (∼ 116 MPa). The large difference of strain hardening behaviour between ferrite and austenite phases is ascribed to a martensitic transformation. Thus, the transformation-induced plasticity effect in retained austenite is the main contributor to the strain hardening during Lüders deformation of the present medium-Mn steel.
