resistance and inhibition of diffusion of chromium. After exposure in air at 800 ℃for 1000 h, the interfacial resistance of LSF20-coated alloy is lowered by more than 23 times to that of LSM20-coated......
Effect of Rare Earths on Hot Cracking Resistant Property of Mg-Al Alloys Guo Xutao1,Zeng Daben1,Zheng Weichao2,Tang Bin3,Li Shuangshou2 (1.Department of Mechanical Engineering;2.Fundamental Industry Training Center;3.Department of Engineering Mechanics, Tsinghua University, Beijing 100084, China) ......
points of view for its intricate pattern selection mechanisms and useful industrial application. Most study of non-equilibrium is about the metal, alloy and other simple system. The complex silicate......
is the critical value for the magnetic properties change. Below this value, Br increases slowly meanwhile Hci and (BH)max decrease strongly because alloy contains extra fractions of soft magnetic phase......
Influence of Lanthanum on Tribological Properties and Microstructure of Laser Clad B+Fe+Si Composite Coatings 程西云1,谢学兵1,蒋松1 (1.Department of Mechatronic Engineering,Shantou University,Shantou 515063,China) Abstract:The effects of rare earth ferrosilicon on the microstructure and anti-wear properties of laser-clad Fe-based alloy coating were investigated. The composition of Fe,B4C and rare......
to the inferior mechanical properties of the fly ash particles, the tensile strength of the FA/Al composites was lower than that of the corresponding aluminum alloy matrix and was 70.1 MPa and 180.6... alloy-fly ash(FA) composites are with low density, low cost, and improved wear resistance [1-3]. The composites can find potential applications in automotive, aerospace components, machine parts......
Abstract: The influence of supercooled melt forced lamina flow on microsegregation was investigated. The concentration distribution at solid-liquid boundary of binary alloy Ni-Cu was simulated using...]. Great achievements are obtained on pure material to alloy [9-11], isothermal to non-isothermal [12-14], supercooled melt without flow to that with flow [15-18] and so on [19-21]. However......
of thin films is better than that of aluminum alloy when the sintering temperature is higher than 300 ºC. And the excellent corrosion protective effect is obtained by single-layer coating when......
dissolution during weld brazing. Finally, the influences of the addition of alloy element on mechanical performance of the welding joints were studied and the design principles of filler metals for weld......
