摘　　要：采用传统挤压铸造工艺制备了Al18B4O33晶须增强6061铝基复合材料,为提高复合材料的热轧变形能力预先对Al18B4O33晶须表面进行了低熔点金属Sn的涂覆,并在500℃实现了复合材料的热轧变形,最终轧制比达到了70%.研究表明,低熔点金属Sn的界面涂覆可以明显提高Al18B4O33/6061Al复合材料的高温塑性,并且对轧制复合材料Al基体中织构的形成和演化有重要的影响.In this paper,Al18 B4O33 whisker reinforced 6061 aluminum matrix composites were fabricated by traditional squeeze casting technology.In order to improve the hot rolling deformation of composites,the low-melting-point Sn was coated on the surface of Al18B4O33 whiskers in advance.the composites were hot rolled at 500℃and the final rolling ratio reached 70%.The results show that the interface coating of low-melting-point Sn can obviously improve the high temperature plasticity of Al18B4O33/6061Al composites and has an important effect on the formation and evolution of texture in Al matrix of the rolled composites.
