ABSTRACT The refractory high-entropy alloys (RHEAs) have been the subject of considerable research in recent years. Since the Laves phase usually leads to a dramatic decrease in the malleability of RHEAs at ambient temperatures, it is critical to identifying the Laves-phase formation. Here, a facile and effective criterion is proposed to predict the phase stability based on the empirical parameters of reported RHEAs. The results indicate that the small atomic size difference is a sufficient condition for determining the stability of solid solution but not a necessary one. In general, the Laves-phase precipitates can be inhibited by decreasing the atomic-size difference, the enthalpy of mixing, and the valence electron concentration. These criteria can be easily adapted to design new RHEAs with the desired phase structure.

ABSTRACT The composition of precipitates in peak-aged Al-Zn-Mg-Cu alloys with various Zn/Mg ratios has been investigated by atom probe tomography (APT). The results show that the η′ and the T′ phases have different compositions with a similar Zn/Mg ratio in the same alloy. The Zn/Mg ratio within precipitates was shown to be positively correlated with the Zn/Mg ratio in the alloy. Moreover, the size dependency of composition for ageing precipitates in Al-Zn-Mg-Cu alloys has been determined. This study enriches the understanding of precipitate composition relative to that of the bulk in Al-Zn-Mg-Cu alloys.

ABSTRACT LZ7C3 fibres with nanostructures have been synthesised by the sol–gel method combined with electrostatic spinning technology and a high-temperature-resistant LZ7C3 ceramic material prepared by high-temperature calcination. The formation process of the ceramic fibre was studied and its properties characterized by differential thermal analysis, X-ray diffraction and infrared spectroscopy. The microstructure of the fibre was analysed by scanning electron microscopy and transmission electron microscopy, and the properties of the fibre were determined. The results showed that many conditions, such as calcination temperature and silica-sol content, have a pivotal influence on the crystal phase composition and morphology. By comparing the effects of these conditions, ceramic materials with exceptional properties have been prepared.

Recently, Correa et al. [1] conducted experiments on the relationship between solidification parameters, including solidification time ts and secondary dendrite arm spacing λ2, for an Al-3wt.%Cu-3wt.%Ni alloy. Their data for the ts λ2 relationship are presented in Figure 1. Note that there are two regions with very different slopes (i.e. the exponent of ts). The fit to the data by Correa et al. is presented in the figure. Note that the slope in the trend of the data, i.e. the exponent of solidification time, is 0.076 below ts = 70 s – a value significantly less than 1/3. At longer solidification times, the exponent of the solidification time is 0.251, a value approaching 1/3, which is consistent with coarsening. The reason for the existence of two distinct regions is unknown. Correa et al. applied the Rappaz-Boettinger [2] and Tiryakioğlu [3] models for the ts λ2 relationship to their dataset and reported that both models overestimated λ2 significantly. We note that Correa et al. used a surface tension value of 1.29 N/ m, rather than the solid–liquid interfacial energy, in their calculations. This is consistent with their previous studies [4]. We contend that the approach taken by Correa et al. is erroneous on account of the following reasons:

ABSTRACT Coal is an important energy and chemical raw material. Carbonization is an effective way for comprehensive utilization of coal, especially for coal with coking capability. The complex pore structure of raw coal and its carbonization solid products can be well characterized by a fractal description. Owing to a lack of in situ studies, the change in the fractal structure of coal with coking capability during carbonization remains unclear. Here we report briefly on an in situ study on high-temperature (1000°C) carbonization of four kinds of Chinese typical bituminous coal with coking capability, namely gas coal, fat coal, coking coal and lean coal, by synchrotron radiation small-angle X-ray scattering (SAXS). The change of fractal structure of the coal is analyzed in terms of corresponding mechanisms.

ABSTRACT This experimental study deals with the effect of modifying an Si-rich LM6 cast alloy by ball milling with Si/Al powder particulates in which alloying was conducted via semi-solid liquid processing. The cast alloys were analyzed via their tensile properties with a microstructural evaluation of their fractured surfaces. The tensile results reveal the influence of ball-milled Si-rich powdery chips on the cast materials and demonstrate an improvement in tensile properties for 10% (R = 0.1) and 25% (R = 0.25) addition of reinforcement particulates. The combined effect of processing and the presence of Si-rich particulates is identified on the fractured surfaces. The results also show that higher values of tensile stress and Young’s modulus are obtained for the R = 0.1 samples but that the strain was higher for the R = 0.25 samples. A mechanism and model for the tensile fracture, and particle and interface cracking are proposed according to microstructure and EDX observations.

ABSTRACT Grain refinement is significant for the mechanical properties of engineering alloys. We achieved a bi-ultrafine microstructure in an Mg–12Gd–3Y–0.5Zr alloy through equal channel angular pressing (ECAP) at 300°C. The ECAP not only refined the matrix grains but also broke the large intermetallic particles into fine secondary particles and then rearranged them at the grain boundaries. These fine particles can suppress the growth of the recrystallised grains, as well as promote nucleation for recrystallisation. After four passes of ECAP, a uniform microstructure with both the matrix grain (∼500 nm) and the particle size (∼300 nm) in the ultrafine range was obtained. This unique microstructure resulted in a good combination of strength (>300MPa) and elongation to failure (>35%) at 200°C, which sheds new light on refining microstructure to obtain good mechanical performance at elevated temperatures for Mg alloys.

ABSTRACT In this work, Ni-Ti shape-memory alloy (SMA) plates were laser welded using different laser powers. A systematic trend of decreasing deterioration in nanomechanical properties – including superelastic recovery – from the weld centre, through the interface region and the heat-affected zone to the base–metal regimes has been observed. The extent of the deterioration increases with increasing laser power. The observations are explained in terms of a decreasing cooling rate and increasing austenite finish temperature (Af ) with an increase in laser power.

ABSTRACT Grain-growth kinetics of high-entropy, single-phase, face-centred cubic (FCC) Al0.2CoCrFeNi alloy was studied by isothermal annealing over a wide temperature range for different time intervals. Both optical and EBSD studies show a significant amount of annealing twins. Data were analysed using classical grain-growth models and the activation energy was estimated using the Arrhenius type equation. The grain-growth exponent was found to be n = 3 and the measured activation energy for grain growth was 190 ± 15 kJ mol−1. Significant resistance to grain growth was observed at 1100°C. Microstructural characterisation tools like EBSD, along with nanoindentation, was used to understand the observed behaviour.

ABSTRACT A friction-stir welded Al–Cu–Li alloy plate with desirable mechanical performance has been obtained using specific parameters. The microstructures of the nugget zone were systematically characterised and nano-sized phases, including , and were found in its matrix. These phases enhance the strength of the joint to a level comparable with the base metal. The results provide the means of obtaining a reliable and low-cost friction-stir weld (FSW) joint for T3-tempered Al–Cu–Li alloy plates without any post-welding heat treatments. This study shows that, by using appropriate parameters of FSW, the microstructures and mechanical precipitates of the nugget zone can be controlled to enhance the weld quality.
