| 摘 要： | 研究搅拌摩擦加工工艺对Al3Zrp/6063铝基复合材料组织性能的影响。该复合材料在6063-5%(K2ZrF6)体系下原位内生获得,利用OM、XRD、SEM观测原位内生颗粒Al3Zr的形貌、分布及尺寸,分析材料性能。实验分析可得:经搅拌摩擦处理后,复合材料的增强体更加细小均匀;基体晶粒破碎,晶粒形状发生改变;材料的抗拉强度变大,延伸率变大;具有超塑性,在变形温度500℃,应变速率1.67×10-2s-1,材料的延伸率达348.16%。

| Abstract: | The effects of FSP (friction stirring processing) on microstructure and properties of the Al3Zr/6063Al composite were investigated, which was obtained in 6063-5wt%(K2ZrF6) system. OM, XRD and SEM were used to observe the morphology, distribution and dimensions of in-situ Al3Zr particles, and then the properties were analyzed. It is found that reinforcement particles of the composite are finer and more uniform after FSP; matrix grains crush and grain shape changes; tensile strength and elongation become larger; the composite shows superplastic deformation, especially when the deformation temperature is 500 oC and strain rate 1.67×10-2 s-1, it achieves 348.16% elongation rate. |
