Stored energy analysis of Zn—5Al eutectic alloy in superplastic deformation

The stored energy and the energy release during SPD(superplastic deformation)of a Zn-5Al alloy were studied.The alloy after rolling process gains more stored energy,and the as-rolled speciment can obtain maximum elongation and minimum flow stress without hot loding treatment before SPD.Experimental results show that stroed energy release process is along with SPD process and is also an impetus to SPD.The as -rolled Zn-5Al alloy has 48J/mol stored energy which was measured with DSC(differential scanning calorimeter)and conforms well to the calcuated value.The as-rolled Zn-5Al alloy after SPD with an elongation of 2500% releases 112J/mol stored energy,Analysis shows that the strain rate is in direct ratio to the rate of stred energy release.

The cyclotron autoresonance maser with a large-orbit electron ring in a dielectric-loaded waveguide

The cyclotron autoresonace maser with a large-orbit electron ring in a dielectric-loaded waveguide has been analyzed. The stability properties are investigated self-consistently on the basis of the linearized Vlasov-Maxwell equations. The numerical results show the growth rate increases when the electron rotating ratio increases. And the dielectric liner can greatly reduce the energy of the electron beam.
