摘要

设计了低稀土含量的Mg-6Gd-1Er-0.5Zr(GE61K)合金，采用快速轧制的方法制备了合金板材，获得了屈服强度、抗拉强度及伸长率分别为201 MPa、248 MPa及17.4%的GE61合金板材。该板材经退火处理后，强度略微降低，而伸长率可提升至20.7%。固溶强化、织构强化是影响合金板材力学性能的主要因素。

Abstract

Mg-6 Gd-1 Er-0.5 Zr（GE61 K） alloy with low rare earth content was designed. The alloy sheet was prepared by rapid rolling. The yield strength

tensile strength and elongation of the alloy sheet reach up to 201 MPa、248 MPa and 17.4%

respectively. After annealing tretament

the strength of the sheet is decreased slightly

however the elongation can be increased to 20.7%. Solution strengthening and texture strengthening are the main factors affecting the mechanical properties of the alloy sheet.
