中文摘要:用25ppi 泡沫陶瓷器过滤净化铝镁合金熔体实验,对比分析了经过滤和未经过滤试样的抗拉强度和伸长率,并对试样断口进行了扫描电镜分析和能谱分析。结果表明,过滤后,合金试样的力学性能改善。
英文摘要:Al-Mg alloy melten was filtered with 25 ppi CFF. The tensile strength and extension ratio of samples with and without filtering were analyzed contrastively. Furthermore, the fracture was analyzed by SEM and EDS. The results show that the mechanical properties of the samples improve.
