摘要
钼-铼(Mo-Re)合金的纹理在热加工过程中不可避免。[110]和[100]是 Mo-Re 合金中常见的取向,会影响机械响应。然而,Mo-Re 合金中机械响应的取向依赖性尚不十分明确。为了澄清这一问题,我们分别对取向为 [100] 和 [110] 的晶粒进行了微柱压缩试验。在 Mo-14Re 和 Mo-42Re(重量百分比)中发现了与取向相关的压缩特性,但在 Mo 和 Mo-5Re 中却没有发现,这可能是由于 Re 增加时激活了多滑移平面。Re 的固溶效应不仅取决于取向,还取决于 Re 的含量。[100]和[110]Mo-5Re中都出现了软化效应,而[110]Mo-14Re和Mo-42Re中则出现了强烈的强化效应。我们的研究表明,要获得良好的强化效果,应优先选择具有[110]取向/质地的 Mo-Re 合金。
Orientation‐dependent mechanical responses in molybdenum‐rhenium alloys evaluated via micro‐pillars
Textures in molybdenum‐rhenium (Mo‐Re) alloys are inevitable during thermal fabrication. [110] and [100] are common orientations in Mo‐Re alloys and effect mechanical responses. However, orientation dependence of mechanical responses in Mo‐Re alloys is not quite clear yet. To clarity this problem, micro‐pillar compression tests are conducted in grains with orientation [100] and [110] separately. Orientation‐dependent compressive properties are found in Mo‐14Re and Mo‐42Re (wt.%), but are not found in Mo and Mo‐5Re, which may be attributed to activated multi‐slip planes as increased Re. Solid solution effect of Re not only relies on orientations, but also on Re contents. Softening effect occurs in both [100] and [110] Mo‐5Re. while, strong strengthening effect happens in [110] Mo‐14Re and Mo‐42Re. Our research clarifies that Mo‐Re alloys with [110] orientation/texture could be preferred to obtain good strengthening effect.
