Elevated Temperature Tensile Properties and Microstructure of Carbon Nanotubes/ZM5 Alloy Composites
摘 要
在氩气保护下,采用搅拌铸造法制备了碳纳米管(CNTs)/ZM5镁合金复合材料;测试了铸态下其高温拉伸性能,并对其显微组织和断口形貌进行了分析.结果表明:该复合材料具有良好的高温拉伸性能,在拉伸速率为1 mm·min-1以及温度为473 K时其抗拉强度可达117.65 MPa,比基体提高了20%;当CNTs加入量为0.5%时,其最大伸长率达到8.32%,比基体提高了2162%;在高温下该复合材料的断裂形貌主要由韧窝和撕裂棱所组成.

Abstract
Carbon nanotubes(CNTs)/ZM5 alloy composites were fabricated by stirring casting method with the protection of Ar.High temperature tensile properties of the composites were tested and the fracture sections were observed via SEM.The results show that the CNTs/ZM5 alloy composites has good tensile properties at high temperature.When the tensile rate was 1mm/min,the tensile strength of the composites was up to 117.65 MPa at 473 K,increased by 20% to the as-cast ZM5.While the maximum ductility of the composites was 8.32% at the 05% addition of CNTs,enhanced by 21.62% to the as-cast ZM5.And the fracture mode of the composites mainly consisted of dimples and tear edges at the elevated temperature.
