In this study, the AlFeNiTiZn high entropy alloy was successfully produced in powder form by the mechanical alloying process. Characterization of the ball-milled product by X-ray diffractometry (XRD), scanning electron microscopy along with energy dispersive spectroscopy (SEM-EDS), and...

Abstract: The microstructure refinement mechanism and mechanical properties of 6082 aluminum alloy with different content of rare earth La element were investigated. The results showed that the addition of La can refine the α-Al grains, change the volume fraction of the Mg 2 Si particles and...

The effects of further addition of Al element (AZ91-0.7CaO-1Al (wt.%), AZCA) on microstructure, corrosion resistance and mechanical property of AZ91-0.7CaO (AZC, wt.%) alloy were investigated with the comparison of commercial AZ91 (AZ91) alloy. The result showed that the addition of Al could...

Due to the extremely harsh environment in the fusion reaction, the device often faces transient thermal shocks (TTS), which would inevitably cause significant effects on the microstructures and performance of the structural materials. In this study, a reduced activation VCrFeTa 0.2 W 0.2...

Additively manufactured superalloys have attracted increasing attention due to their inherent hierarchical microstructure, however are plagued by anisotropic properties originated from columnar grains. In this work, scandium was introduced as an oxide dispersion strengthener (ODS) into the...

Sintering schedule has important effect on the microstructure and electrical properties of ZnO varistors, but the study of sintering temperature is deficient. In this paper, the effect of sintering temperature on the microstructural evolution and electrical properties of ZnO-Bi 2 O 3 based...

Due to the rapid cooling rate (230 mm/s) and large temperature gradient (107°C/m) produced by the self-propagating high-speed heat source, the liquid solder solidification procedure is extremely non-equilibrium, implying that the solder's original microstructure will invariably have a...

In the current research, AlCoCrFeNi–x wt.% NiTi (x= 0, 5, and 10) composites were prepared using a combination of mechanical alloying (MA) and spark plasma sintering (SPS) methods. Microstructural studies showed that the introduction of 5 wt.% NiTi slightly changed BCC and FCC contents of the...

A novel grain boundary diffusion process with low-pressure technology was employed to develop Nd-Fe-B sintered magnet samples as thick as 2mm. The uniform and successive Nd-rich phase in the low-pressure diffused magnets promotes Tb atoms to permeate inside the magnets, and the diffusion depth...

In this study, the application of laser processing technology to produce the wedge surface and its internal structure in one-step way will be introduced, and the function of wedge surface and internal structure coupling on liquid’s movement and controlling will be studied. Inspired by the...
