项目摘要

Anisotropy of strengthening by solid solution and precipitation in concentrated Mg-Al and Mg-Zn alloys. The addition of solute increases the strength of Mg in some crystallographic directions but weakens the material in others. The weakening is called solid solution softening, and it can have profound effects on the mechanical behaviour of the material. Solid solution softening has been observed in the prismatic planes of single crystals of dilute Mg-Al and Mg-Zn alloys. Easier prismatic slip lowers the strain hardening rate and increases the ductility of polycrystalline alloys in comparison with pure Mg. Despite their obvious significance, these effects have not been studied in single crystals of concentrated alloys. This is the main object of this project.
浓Mg-Al和Mg-Zn合金固溶体和析出强化的各向异性。溶质的加入增加了Mg在某些晶体学方向上的强度,但在其他方向上却削弱了材料的强度。这种弱化被称为固溶体软化,它可以对材料的机械行为产生深远的影响。稀Mg-Al和Mg-Zn合金的单晶棱柱面存在固溶软化现象。与纯Mg合金相比,易发生棱柱滑移降低了多晶合金的应变硬化速率,提高了合金的延展性。尽管具有明显的意义,但这些效应尚未在浓缩合金的单晶中进行过研究。这是本项目的主要目标。
