Abstract Scope |
Alloying Mg with Mn improves the strength and the corrosion resistance. The addition of rare earth elements weakens the texture and improves the age hardening response. Nd and Gd are ideal elements to investigate the effect of low and high solid soluble rare earth in Mg on the thermo-mechanical behavior of MgMn. For this purpose a Mg alloy with 1wt.% Mn was modified with an addition of 1wt.% Gd, 1wt.% Nd and with their combination, respectively. In situ synchrotron radiation diffraction was performed during solidification and compression to analyse the solidification sequence of the phases and the deformation behavior of the material. The compression experiments have been performed at room temperature and 350°C up to a deformation of 0.3 with a deformation rate of 10-3 s-1. The compressed samples were subsequently subjected to electron backscattered diffraction to investigate the post mortem microstructure. |
