Electropulsing Treatment

Thermo-electropulsing rolling (TER) process, which combined the electropulsing treatment with the conventional warm rolling process (WR), was applied to manufacture AZ31 magnesium alloy strips in the current study. Influences of TER process and WR process on microstructure and mechanical properties of AZ31 Mg alloy were studied. TER process was found to induce and accelerate the dynamic recrystallization (DRX) behavior of the samples at a relatively low temperature within a short time. Besides, TER process could obtain samples with better mechanical properties than that of WR process.

Grain Diameter

The experiment of ultrasonic cast-rolling magnesium strip was carried out on the horizontal twin-roll cast-rolling machine with the ultrasonic pole used in the solidification. The microstructures of ultrasonic and general cast-rolling magnesium strip were characterized. The results showed that the cellular dendrite of the general cast-rolling magnesium strip was coarse, the grain structure was heterogeneous and the average grain diameter was between 50μm~60μm. However, the grain structure became more homogenize after the ultrasonic treatment for cast-rolling magnesium strip, the grain was refined and the average grain diameter was between 20μm~30μm. Besides, the mechanical properties test results show that the tensile strength, yield strength and elongation of the ultrasonic cast-rolling magnesium strip were increased by 22.85%, 49.78% and 123.06% than those of the general cast-rolling magnesium strip.
