Vacuum brazing of TA1/304 stainless steel (SS) was systematically investigated by adjusting the composition of the filler metal, brazing temperature and holding time. The addition of nickel to the filler metal avoided excessive TixCuy phases on the 304 SS substrate side and eliminated the TiFe...

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 Mg2Si particles and...

NaZn 13 -type La(Fe,Si) 13 alloys are one of the most promising magnetocaloric materials near room temperature. However, the impact of lanthanide doping on their magnetocaloric properties has not been thoroughly investigated. Here, a series of Gd-doped La 1- x Gd x Fe 11.5 Si 1.5 ( x =0, 0.05,...

Borate-based bioglass has attract more interest as a bone repair material due to its good machinability and degradability, but the quick release of boron produce cytotoxicity is a question need be taken into consideration. In this paper, borate-based bioglass scaffolds substituted by 0-9 mol%...

The Fe 3 Cr 2 CoNiAl x (x = 0.6, 0.7, 0.8, 1.0, 1.1, 1.2) multi-principal elements alloys were prepared, and the microstructure and mechanical behaviors were investigated. The crystal structure changed from a dual-phase structure of FCC plus body-centered-cubic (BCC) structure to a single...

The microstructure evolution of 254 super austenitic stainless steel at five typical cooling rates (6-1000 °C min -1 ) were observed by high temperature confocal scanning laser microscopy (HT-CSLM). The results showed that the solidification mode of 254SMO was austenite-ferrite type (AF mode)....

The melt treatment in the magnetodynamic apparatus using the ARSAL refining flux and modification of phosphorous copper were applied to hypereutectic Al-Si alloys to investigate their structural changes and properties. It was shown that such treatment of the melt in the magnetodynamic...

AlxCoCrFeNiCu (x=0.5, 1.0, 1.5, 2.0) high entropy alloy was prepared by powder metallurgy method.The effect of Al content x on microstructure and corrosion properties of high entropy alloy was systematically studied. The results show that the high entropy alloy has simple crystal structure and...

This study developed a novel series of AlCrCuFeNi 2 V x (x=0, 0.3 and 0.6) high-entropy alloys (HEAs), and systemically assessed the relationship between composition, processing, microstructure and mechanical properties. The alloys were produced by arc melting and studied in as-solidified and...

ZnO-Bi 2 O 3 based varistors are usually used as the core element to manufacture surge arresters, but the study of sintering temperature is deficient. In this paper, the effect of sintering temperature on the microstructural evolution of ZnO-Bi 2 O 3 based varistors was studied detailedly....
