What is the relationship between the mechanical properties of AZ91D and process parameters?

What is the relationship between the mechanical properties of AZ91D and process parameters?

2025-07-30

The mechanical properties of AZ91D are mainly affected by casting temperature and die temperature. When the casting temperature decreases (thus increasing the solid phase content), the initial mechanical properties (tensile strength and elongation) tend to decrease due to reduced heat content in the melt, which causes casting defects like cold flow. However, by adjusting process parameters, these mechanical properties can be significantly restored to their initial levels.

 

Additionally, the grain size of AZ91D is controlled by the solidification rate, which is related to the die temperature. Lower die temperatures result in smaller grain sizes: the grain size decreases from about 20 μm at the highest die temperature (275 °C) to approximately 10 μm at the lowest die temperature (50 °C). Correspondingly, the yield strength, tensile strength, and elongation all increase with lower die temperatures. For example, the yield strength rises from 145 MPa at 275 °C to 175 MPa at 50 °C, and the highest values of tensile strength (270 MPa) and elongation (8%) are achieved at 100 °C.
