Summary

The creep resistance of the Mg-Al-base alloys AZ91 and AS21 in the die-cast state was investigated at temperatures up to 150 °C in compression, free from influences of concurrent fracture. AS21 has higher resistance to creep than AZ91 for low stresses < ≈100 MPa. Microstructural investigations including TEM suggest that this difference results from a difference in precipitation hardening.
