Induction plasma spheroidization of tungsten and molybdenum powders JIANG Xian-Liang (蒋显亮)1, M.Boulos2 1. Institute of Surface and Coatings Technology, School of Materials Science and Engineering... on the particle surface of these two metals. The influence of spray chamber pressure on the spheroidization and oxidation phenomena was discussed. The results show that fewer Mo particles than W......
Effect of spheroidization of cementite in ductile cast ironBasavaraj,Pavankumar R.Sondar,Subray R.Hegde摘 要:The research aims to provide an alternative to austempering treatment of ductile cast iron with a simple and cost-effective heat-treatment process. This goal was accomplished by applying a simple one-step spheroidization heat treatment......
Spheroidization behaviour of a Fe-enriched eutectic high-entropy alloyYu Yin1,Damon Kent1,2,Qiyang Tan1,Michael Bermingham1,Ming-Xing Zhang11. School of Mechanical and Mining Engineering... to evaluate the possibility and feasibility of spheroidization of the lamellar structure of the EH EA in order to improve the ductility.Due to the high cooling rate of arc-melting,the as-melted......
On-line spheroidization process of medium-carbon low-alloyed cold heading steelYu Fu,Hao Yu,Pan TaoSchool of Materials Science and Engineering,University of Science and Technology Beijing摘 要:Conventionally manufactured 35CrMo cold heading steel must undergo spheroidization annealing before the cold heading process.In this paper,different types......
Influence of cementite spheroidization on relieving the micro-galvanic effect of ferrite-pearlite steel in acidic chloride environmentHu Liu1,2,Jie Wei1,3,Junhua Dong1,3,Yiqing Chen3,Yumin Wu3,Yangtao Zhou1,Subedi Dhruba Babu1,2,Wei Ke11.

Spheroidization of silica powders by radio frequency inductively coupled plasma with Ar–H2 and Ar–N2 as the sheath gases at atmospheric pressureLin Li,Guo-hua Ni,Qi-jia Guo,Qi-fu Lin,Peng Zhao,Jun-li... treatment at a radio frequency of 36.2 MHz. The effects of the added content of hydrogen and nitrogen into argon(serving as the sheath gas), as well as the carrier gas flow rate, on the spheroidization......
development of lamellar structure of an orthorhombic Ti2AlNb-based Ti-22Al-26Nb-1Zr alloy, including B2 decomposition and spheroidization of O phase, was investigated. The results show that the lamellar... exhibits microstructural instability including the severe dissolution of B2 lamella, discontinuous precipitation and spheroidization of O phase during the long term aging process at 700 °C up to 800 h......
words: Ti-6Al-2Zr-1Mo-1V alloy; cavity nucleation; lamellar alpha colony; dynamic spheroidization 1 Introduction With the nature of the close-packed hexagonal crystal structure and the strong... a certain extent with the temperature increasing and strain rate decreasing. This is reasonable in view of the variation of the volume fraction of beta phase and dynamic spheroidization behavior......

compression, microstructural spheroidization was initiated from plastic instability regions, and it was preferentially activated in vertical lamellae with a growth direction parallel to the compressive direction. Continuous dynamic recrystallization associated with lattice dislocations was the mechanism in both AuSn and Au5Sn multilayers. After spheroidization, strain accumulations were weakened......
