Effects of cryogenic treatment on microstructures and mechanical properties of Mg-2Nd-4Zn alloy

The effects of cryogenic treatment on the microstructures, precipitates, macro-texture and mechanical behavior of the extruded Mg-2Nd-4Zn alloy were characterized. The results indicated that the cryogenic treatment promote to refine grains and the precipitation of the second phases, which play a vital role on the strength of Mg alloys. The enhancement of plasticity of Mg alloys depends on the activation of a base slip, and as well as with the change of macro-texture, which obviously improve plasticity of alloy. Understanding of the macro-texture and microstructures during the cryogenic treatment are of great significance for improving the mechanical properties of Mg alloys.

Automated summary

The cryogenic treatment was found to refine grains and promote the precipitation of second phases, enhancing the strength and plasticity of Mg alloys. Changes in macro-texture also significantly improved the plasticity of the alloy. Understanding macro-texture and microstructures during cryogenic treatment is crucial for enhancing the mechanical properties of Mg alloys.
