techniques were applied, such as thin NdFeB ingot technique, narrow particle distribution on jet mill, low oxygen content control and high aligned magnetic field press. It is necessary to produce thin...Study on Key Techniques for Producing High Performance NdFeB Sintered Permanent Magnets 李红卫1,张深根1,张耀1,徐静1,于敦波1,赵进松1 (1.General Research Institute for Non-Ferrous Metals,Grirem Advanced Materials......
good agreements with practice. Key words: electromagnetic tube bulging; time varying electromagnetic field; magnetic pressure; high velocity deformation; dimensionless length ... and boundary conditions were thoroughly discussed. ANSYS/EMAG was used to model the time varying electromagnetic field in order to obtain the radial and axial magnetic pressure acting on the tube......
-mechanical effect, magnetic leakage field gradually develops along with the appearance of fixed nodes of magnetic domain near crack tip. In stress-concentrated areas, high stress energy is accumulated, while... analyzed and discussed respectively. It is found that MMM signals don’t change with inspecting time-interval, since stress field and magnetic leakage field maintain unchanged at any time after welding......
