Research Of Vacuum Quick Quench For NdFeB

The NdFeB conduct new third generation manget material, currently, Europe, Africa, Southeast Asia market condition is better. In our country the quantity of NdFeB export increases year by year. Currently the western and national the biggest NdFeB customer is the actuator of the calculator peripherals, mosttheeye-catcher is a nuclear magnetic resonance to become to be like an instrument (MRI). From farsighted see, the electrical engineering will be the main customer of the NdFeB . In addition, the water processing and the dirty water decontamination electromagnetism switch manget suspend a conveyance, the vehicle magnetic force machine, the stereo set spare part is also a big customer. The future is the world of the manget , the manget seeps through the large realm of the life, the magnetic levitation railroad train of Germany already the industry turned. The market foreground that prospects the NdFeB is very nice. Key is we can rob to have this big market. Say to the our country, be used as the calculator of the information technique being develop rapidly increasingly universal of today, say to the NdFeB that is a big market.The NdFeB vacuum solidifies quickly's casting technique is one of the key crafts that makes a high performance to burn the knot NdFeB magnet. To get the high performance magnet system, the tiny view organization of NdFeB metal alloy ingot should have the pillar form crystal integrity, no α -Fe to be partial to separate, enrich Nd form dispersion to spread the characteristics for distribute.In this thesis, the metal alloyes getting from several common foundry methods-flat panels to cast, the pillar form cast, the lamella cast etc. were compared by the experiments and the organization of the casting knot was observed by electron microscope.. The magnet powder was made by the method of broken...
