摘要:
通过累积叠轧(ARB)的方法制备Al基非晶/Al层状复合材料, 不仅可以突破铝基非晶尺寸的局限性, 而且利用了轧制过程中析出的部分纳米晶增强复合材料的力学性能。制备了Al86Ni8Y6和Al85Ni5Y8Co2两种非晶薄带, 采用差示扫描量热法(DSC)以及X射线衍射仪(XRD)确定了非晶薄带中初晶α-Al完全析出所需的温度及时间; 通过累积叠轧(ARB)的方法制备了Al/Al, Al/非晶纳米晶/Al层状复合材料并测试了其力学性能。结果表明: 退火温度分别取575,580 K, 退火时间需要控制在45 min以内, 叠轧4次后Al/Al85Ni5Y8Co2/Al的抗拉强度最高, 为226 MPa, 材料的伸长率高达17.4%。
Abstract:
The Al-based amorphous/Al layered composite material is prepared by the accumulative roll bonding(ARB)method, which can not only break through the limitation of the size of the Al-based amorphous material, but also enhance the mechanical properties of the composite material using part of the nanocrystals precipitated during the rolling process. Two kinds of amorphous strips were prepared. The annealing temperature and time of the precipitation of the primary α-Al were determined by the differential scanning calorimetry(DSC)and X-ray diffractometer(XRD). Al/Al and Al/amorphous nanocrystalline/Al layered composite materials were prepared by the method of the accumulative roll bonding, and their mechanical properties were tested. The results show that the annealing temperature is 575 K and 580 K respectively, and the annealing time needs to be controlled within 45 min; after 4 times of rolling, Al/Al85Ni5Y8Co2/Al has the highest tensile strength and hardness of 226 MPa and 49.2 HV respectively, and the elongation of the material is as high as 17.4%.
