Properties and Processing of New Magnesium-Tin-Calcium Alloys for Powertrain and Hand Tool Applications
The development of new creep resistant magnesium alloys has become a major issue in recent years. The developed alloys are based on the binary system Mg-Sn. Sn as major alloying element was chosen due to its high solid solubility over a wide temperature range and due to the possible formation of Mg2Sn intermetallic precipitates with a high melting temperature of about 770℃. These characteristics suggest that a fairly large volume fraction of thermally stable Mg2Sn particles can be formed during solidification. This makes it possible that the Mg-Sn alloys can be developed as creep resistant magnesium alloys and/or wrought magnesium alloys. Previous investigations indicate that the Mg-Sn alloys have a comparable or even better creep property than AE42 alloy. The present paper presents an overview about recent major works on the developments of Mg-Sn alloys performed in MaglC,GKSS Research Center, which includes: microstructural characterization,creep,deformation and hot deformation, and corrosion behavior. Very positive results have been obtained and show Mg-Sn-Ca alloy systems can be developed for powertrain and hand tool applications.
