Magnetic Properties of Nd12Co6Pb Compound () Abstract:The magnetic and magnetocaloric properties for the Nd12Co6Pb compound were investigated. The Curie temperature TC of the magnetic transition of Nd12Co6Pb compound is 194 K. The experimentally determined magnetic effective paramagnetic moment is μeff=12.36 μB per formula unit (3.49 μB per Nd atom). The maximum magnetic entropy change......

Abstract: The mathematic model of a high pressure and large flow capacity water valve with relief unit in large die forging hydraulic press was established and simulated. Then the opening force......
cooling rate and superheating. The decrease of cooling rate and superheating enhance the refinement effect of the low voltage pulsed magnetic field. The magnetic force and the melt flow during... under different thermal controls is not clear. Furthermore, the refinement mechanism of the pulsed magnetic field also needs to be further investigated. The variation of magnetic force and the flow field......
and tangentialvelocity components due to increasing value of magnetic parameter (M). The effect of Hartmann number is to diminish the velocity magnitude. Magnetic field creates Lorentz force, which acts against in the direction of fluid flow. This kind of opposing force diminishes fluid velocity. So the magnetic field is working towards weakening the velocities in the region along the disks. There is also a strong......
