Title: Aiming at enhancing the creep resistance of magnesium alloyed by rare-earth elements
Abstract:
The creep resistance of Mg alloys is usually very poor, leading to the difficult application of Mg products in the aerospace and transportation fields. Adding rare-earth elements is one of the common methods for developing creep-resistant Mg alloys. However, short aging response in the low rare-earth alloyed Mg and wide precipitate-free zones in the high rare-earth alloyed Mg make the creep resistance still non-ideal. For the sake of enhancing the creep resistance of Mg alloys, this work aims to study the real reason for the poor creep resistance and try to find the effective methods for enhancing the creep resistance. Taking the compressive creep behavior of pure Mg (0Y alloy) and various Mg-Y binary alloys (0.15Y, 1.5Y, 4.5Y, 7.5Y and 10.5Y alloys) as an example, the crept microstructures and the creep resistance are analyzed. Then, focusing on the different Y contents, different methods are put forward and proven to successfully enhance the creep resistance. Finally, the mechanisms for the enhanced creep resistance are deeply illustrated.
