摘要：

The addition of Ca into Mg-(3-9)wt%Al alloys increased the hardness at the high temperatures up to 350 degrees C. In particular, this was remarkable when the mass ratio of Ca to Al was higher than 0.8, probably owing to the precipitation of the Mg,Ca phase in the alloys. Such alloys with the Ca/Al mass ratio higher than 0.8 showed excellent heat resistance at a moderate temperature. Therefore, they were considered to be the new promising light-weight heat-resistant alloys for interior automotive applications.
