Simulation on temperature field of TIG welding of copper without preheating LEI Yu-cheng(雷玉成), YU Wen-xia(郁雯霞), LI Cai-hui(李彩辉), CHENG Xiao-nong(程晓农) School of Materials Science and Engineering... of tungsten inert gas(TIG), a model of non-steady three-dimensional temperature field for red copper’s TIG welding with a locomotive arc was established. The temperature field of welding pool was calculated......
Properties of nanocrystalline copper prepared by vacuum-warm-compaction method CHU Guang(楚 广)1, 2, LIU Wei(刘 伟)1, YANG Tian-zu(杨天足)1, TANG Yong-jian(唐永建)2 1. School of Metallurgical Science... with larger pressure, longer duration of pressure or higher temperature. The highest microhardness of nanocrystalline Cu is 3.8 GPa, which is 7 times higher than that of coarse-grained copper......
. In order to improve the situation, we took advantage of rare earth (RE) mineral resource and successfully developed the non-argent Lanthanum-tellurium-copper alloy as a substitute for industry argent-copper. In our research, we were able to successfully apply rare earth lanthanum to copper alloy. The defects as porosity, inclusion, etc. originating from nonvacuum melting processing were controlled. Fine......
. Whilst adding copper to iron did not change the carburisation kinetics, cementite formation and coke morphology, copper alloying reduced nickel and nickel-base alloy dusting rates significantly...Metal Dusting-Mechanisms and Preventions () 摘要:Metal dusting attacks iron, low and high alloy steels and nickel-or cobalt-base alloys by disintegrating bulk metals and alloys into metal particles......
of 12-14 mm were fabricated by the laser melting deposition in a newly patented laser melting furnace[22]. The alloy powder delivering in an argon shielded water-cooled copper-mold was melted by a high-power... Abrasive wear property of laser melting/deposited Ti2Ni/TiNi intermetallic alloy GAO Fei(高 飞), WANG Hua-Ming(王华明) Laboratory of Laser Materials Processing and Manufacturing, School of Materials......
; The amorphous Fe-Ni-W alloy deposits were plated on the surface of AISI 1045 steels and copper alloys. The deposits were obtained through the following procedures: burnishing-polishing-degreasing-wash- ing..., such as AISI 1045 steels and copper alloys. Table 2 Corrosion resistance of Fe-Ni-W alloy deposits on different substrates 2) Under dry sliding condition, the chromium deposit is worn more......
Trans. Nonferrous Met. Soc. China 25(2015) 3953-3958 Microstructure evolution of alumina dispersion strengthened copper alloy deformed under different conditions Ling LI1, Zhou LI1,2, Qian LEI2, Zhu...: Microstructure and texture evolution of Cu-0.23%Al2O3 dispersion strengthened copper alloy, deformed at room temperature or cryogenic temperature, were investigated. The main textures in hot-extruded......
