by XRD, SEM, DSC and TG-DTA. The results show that the material Li1+xV3O8 with good crystallization degree and good thermal stability is obtained at 420 ℃. The electrochemistry test of Li1+xV3O8......
decreases. Disintegration and spall on the Ni-W-P deposits heated at 400 ℃ for 1 h were generated after abrasion test because of the excessive stress caused by different coefficient of thermal......
was measured via tensile test. The results show that the joint has dual characteristics and can be divided into a welding part on the aluminium side and a brazing part on the titanium side. An intermetallic......
of the precipitated phases of Al-4%Cu alloys aged at 130 ℃ were investigated by differential scanning calorimetry analysis, Vickers micro-hardness test, electron probe microanalysis and transmission......
, DU Sui-geng, BAI Jian-hong (College of Materials Science, Northwestern Polytechnical University, Xi’an 710072, China) Abstract: By means of optical microscopy, EDX analysis and tensile test......
rupture strength test. The results show that the cobalt content in the Co-rich layer increases with prolonging carburizing time, the transverse rupture strength of samples increases when carburizing......
of carburizing processes on the gradient structure and hardness of WC-Co gradient cemented carbides were investigated by optical microscopy, scanning electron microscopy and Vickers hardness test. The results......
curves of Ti-3%Al-5%Mo-4.5%V alloy with a wide range of strain rates were investigated under uniaxial quasi-static tension and uniaxial dynamic compression respectively with Instron 8032 test machine......
electron microscopy (HREM) and tensile test. Guinier preston (GP) zone and h′ phase are the main precipitates in original 7050 alloy. The orientation relationship between h′ and matrix is  ......
’s technology test. The results show that the TiZr alloy hydride/NaAlH4 composite has good reversible hydrogen storage properties. The hydrogenation and dehydrogenation kinetics of NaAlH4 can......
