Notes:
The semi-solid compression deformation behavior of the AZ91D alloy with non-dendriticstructure, which was obtained under the semi-solid isothermal treatment condition of 570℃×60min,was studied by means of Gleeble-1500 thermal-mechanical simulator. When the compression strainwas lower than 0.7, along with the compression strain increasing, the compression stress firstlyincreased rapidly, then decreased rapidly, and finally kept a constant stress level gradually. Under thecondition of different deformation temperatures and deformation rates, the maximum compressionstress was obtained simultaneously when the compression strain value was 0.025 approximatively.Furthermore, when the deformation rate kept a constant, the compression stress decreased along withthe deformation temperature increasing, and when the deformation temperature kept a constant, thecompression stress increased along with the deformation rate increasing
