For the hyperdeformations in the actinide nuclei, the theoretical predictions, experimental methods, primary results and existing problems have been discussed.

Effect of holding time on high temperature microstructures of hydrogenation TC4 alloy before superplastic deformation;

This paper studied the superplastic deformation behavior of enhanced titanium-base composite material in-si- tu autogenesis TiB and TiC under conditions of temperature varied in the range of 920～1080℃ and initial strain rate was 2× 10~(-2)s~(-1)～10~(-4)s~(-1).

Optical microscope and scanning electronic microscope ( SEM) were employed to observe the microstructure evolution and fracture behavior in superplastic deformation of AZ31 Mg alloy and the values of deformation activation energy at various.

This process is to combine the superplastic deformation of steel with the heattreatment.

In the previous publications, the assignments of spin values of the superdeformed bands in A≈50 region are not consistent by different methods.

The superdeformed bands in the A-190 region are systematically analyzed using four-parameter rotational spectra formula of Bohr-Mottelson s I(I+1) expansion .

Five superdeformed bands observed in 149 \ Tb were investigated comprehensively.
