We investigate the dimensional transition and carrier dynamics in CdxZn(1-x)Te/ZnTe nanostructures with various Cd mole fractions, grown on Si substrates. Atomic force microscopy images show that the dimensional transition from quantum dots (QDs) to quantum wires occurs with increasing Cd mole fraction. The activation energy of the electrons confin...
This study aimed to determine the optimum processing conditions for dynamic globularization of Ti-6Al-4V alloy having martensite microstructure, and to achieve enhanced superplasticity. A series of isothermal compression tests was carried out for martensite microstructure in the strain range of 0.6-1.4, the strain rate range of 10(-3) S-1 to 1 S-1 ...
The low-temperature superplasticity of ultra-fine-grained (UFG) Ti-6Al-4V was established as a function of temperature and strain rate. The equiaxed-alpha grain size of the starting material was reduced from 11 to 0.3 mu m (without a change in volume fraction) by imposing an effective strain of similar to 4 via isothermal, equal-channel angular pre...
