The Role of Zn on the Elevated Temperature Compression Behavior of Mg5Nd: An In Situ Synchrotron Radiation Diffraction Study

摘要

As-cast Mg5Nd, Mg5Nd3Zn, Mg5Nd5Zn and Mg5Nd7Zn alloys were investigatedwith in situ synchrotron radiation diffraction during compression at350C. The results and the post-mortem microscopy investigations suggestthat twinning was active during deformation, and was most pronounced in thebinary alloy whereas in the ternary alloys grain rotation could be observed.Sub-grain formation could be detected in all the alloys. The reinforcingcapacity of the intermetallic network was the largest in Mg5Nd and Mg5Nd3Zn.
