Steady state creep during transformation in Cd-Zn alloys
Apparent steady-state creep of Cd--2 wt.% Zn and Cd--17.4 wt.% Zn alloys has been studied under different constant stresses ranging from 6.4-12.7 MPa, near the transformation temperature of 483K. The strain rate of the steady-state creep for both compositions has shown two temperature regions of def...

| description | Apparent steady-state creep of Cd--2 wt.% Zn and Cd--17.4 wt.% Zn alloys has been studied under different constant stresses ranging from 6.4-12.7 MPa, near the transformation temperature of 483K. The strain rate of the steady-state creep for both compositions has shown two temperature regions of deformation, the low-temperature region ( < 483K) and the high-temperature region above this temperature. The stress exponent m' was found to change from 4.7 to 2 for Cd--2 wt.% Zn and from 3.1 to 2.4 for Cd--17.4 wt.% Zn alloys. The activation energies in the temperature region below the transformation temperature have been found to be 84 kJ /mole for Cd--2 wt.% Zn and 70 kJ/mole for Cd--17.4 wt.% Zn alloys characterizing the mechanism of volume self-diffusion in Cd.
