Intensification of pretreatment and pressure leaching of copper anode slime by microwave radiationYANG Hong-ying(杨洪英)1, MA Zhi-yuan(马致远)1, 2, HUANG Song-tao(黄松涛)2, LV Yang(吕阳)1, XIONG Liu(熊柳)1(1... 100088, China)Abstract:The application of microwave irradiation for pretreatment of copper anode slime with high nickel content prior to pressure sulfuric acid leaching has been proposed. The microwave......
Simulation and experimental study of high pressure switching expansion reduction considering real gas effectLUO Yu-xi(罗语溪)1, ZHANG Yan-jun(张彦军)1,2, GAO Yu-bao(高玉宝)1, WANG Xuan-yin(王宣银)3, XU Zhi-peng...) uses a switch valve instead of the throttle valve to realize electronically controlled pressure reduction for high pressure pneumatics. A comprehensive and interactive pneumatic simulation model......
Magnetic properties and thermal stability of anisotropic bonded Nd-Fe-B magnets by warm compactionY.Honkura,H.Mitarai,K.Noguchi摘 要:Anisotropic bonded magnets were prepared by warm compaction using anisotropic Nd-Fe-B powder. The forming process, magnetic properties, and temperature stability were studied. The results indicate that the optimal......

Theoretical basis......
treatment at higher temperature have no obvious recover phenomenon.The uneven actions of pressure and temperature in autoclave treatment may be helpful for us to search a new method to improve the magnetic...Structure modification and recovery of amorphous Fe73.5Si13.5B9Nb3Cu1 magnetic ribbons after autoclave treatment:SAXS and thermodynamic analysisL.Y.Guo1,X.Wang1,K.C.Shen1,K.B.Kim2,S.Lan3,X.L.Wang4,W......
: The nanocrystalline Fe82Nb7B10Cu1 soft magnetic ribbons were treated with the mixture gas flow of ammonia and hydrogen at 673 K. The influence of the nitridation treatment was studied by the low-frequency permeability spectra. The result shows that this kind of nitridation treatment can improve the soft magnetic properties under some application conditions. The reason for the improvement of the soft magnetic......
