Uniaxial compression tests on semi-solid AZ61 alloy fabricated by stain-induced activation (SIMA) process and the conventional casts were carried out using the Gleedle-1500 dynamic material testing machine. The relationships between stress and stain were analyzed. The numerical relationships among processing parameters (strain rate z ε& strain z ε temperature T liquid volume fraction L f ) and stress were studied. The proposed constitutive equation was established for semi-solid AZ61 magnesium alloy using the multiple nonlinear regression method. A scientific basic provided for both numerical simulation of processing process of semi- solid AZ61 alloy and rational choice and control of processing parameters.

The Matrix

Thermal compression tests of AZ61 magnesium alloy were performed at deformation temperature 25-400°C with strain rates ranged from 0.02 to 20 s-1, and the microstructure was studied. The conventional dynamic recrystallization (DRX) and shear zones were observed on grain boundaries at temperatures above 200°C. The shear zone and the temperature rise are considered to be responsible for the fracture of specimens. For the large internal stress concentration in the shear zones and the deformation incompatibility between matrix and shear zones, the fracture grew along with the shear zones and the failure occurred in the large deformation field of the matrix at the high strain rate 20 s-1 even at 400°C.
