The creep behavior of a binary Mg-15 wt.% Gd alloy was investigated over the temperature range from 523 K to 743 K, i.e., in both single-phase region (the hexagonal close-packed solid solution Mg) and two-phase plus Mg5Gd precipitates). prepared by squeeze casting technique. In higher range, at 723 specimens were treated situ annealing prior testing. At 673 below, tested cast state. interpreted...

Superior creep strength of a heat resistant AX52 magnesium alloy is ascribed to the grain boundary eutectic Al2Ca phase covering the primary -Mg grains. The eutectic phase is stable in morphology at temperatures below 473K, while it collapses during long term exposure at temperatures higher than 473K. The microstructural change of the alloy during high temperature exposure is characterized by t...

In this study, we deformed the single β phase Mg–Li alloy, Mg–16Li–4Zn–1Er (LZE1641), with conventional rolling (R) and multi-directional (MDR), both at cryogenic temperature. Results showed that nano-precipitation MgZn2 appeared in alloy after MDR, but phenomenon was not present R. The finite element simulation result different deformation modes changed stress distribution inside which affecte...
