Abstract When a longitudinal magnetic field is superimposed to a low pressure plasma, reversal of the radial ambipolar electric field takes place at a definite magnetic field Br. From the Br-values electron temperatures Te in the plasma can be found, when classical magnetic field diffusion exists. In the negative H2-and He-glow plasmas with superimposed longitudinal magnetic field, electron temperatures have been measured on the one hand by the method of electric field reversal and on the other hand with Langmuir probes. There is a fairly good agreement between the Te-values obtained by both methods.

The numerical simulation and experimental measurement of temperature distribution in electrical field activated sintering of titanium powders were carried out. The simulated and experimental results were in good agreement. It was shown that the sintering temperature gradually decreased from the center of sample to the outer. To improve the performance of sintered material, the sintering temperature gradient had to minimize. A method, electric field-activated sintering coupled with axial alternating magnetic field, was proposed to homogenize sintering temperature field. The simulation of sintering temperature field was also conducted under different magnetic field intensity. It was proved that the maximum radial sintering temperature difference in sample was reduced by about three fourths, owing to the skin effect of induced current caused by alternating magnetic field.
