文章亮点

(1) 通过优化合金成分和加工工艺，同时提高了合金的强度和塑性，研究出了一种新型且低成本的Mg–Al–Ca–Zn–Mn合金。

(2) 合金的高强度主要与超细的动态再结晶晶粒、未再结晶区高密度的位错以及α-Mg基体中分布的高密度的纳米析出相有关。

(3) 合金的高塑性主要归因于较高的再结晶体积分数。

中文摘要

本文研究了一种新型低成本兼具高强度和高塑性的Mg–Al–Ca–Zn–Mn合金。挤压态Mg–1.3Al–1.2Ca–0.5Zn–0.6Mn (wt%)合金表现出了高的强度，屈服强度达到411 MPa，同时具有优异的塑性，延伸率达到8.9 %。微观组织表明，Mg–Al–Ca–Zn–Mn合金的高强度主要与超细的动态再结晶晶粒有关，同时还与未再结晶区内高密度的残余位错以及α-Mg基体中析出的高密度纳米析出相有关。合金的高塑性可以归因于高体积分数且具有随机取向的动态再结晶晶粒，以及在未再结晶区内形成的高密度亚晶组织。

Abstract

Abstract

A novel low-cost Mg–Al–Ca–Zn–Mn-based alloy was developed to simultaneously improve its strength and ductility. The high yield strength of 411 MPa and the high elongation to failure of ~8.9% have been achieved in the as-extruded Mg–1.3Al–1.2Ca–0.5Zn–0.6Mn (wt%) sample. Microstructure characterizations showed that the high strength is mainly associated with the ultra-fined dynamically recrystallized (DRXed) grains. Moreover, high-density dislocations in the un-DRXed region and nano-precipitates are distributed among the α-Mg matrix. The high ductility property can be ascribed to the high volume fraction of DRXed grains with a much randomized texture, as well as the formations of high-density subgrains in the un-DRXed grain regions.
