Ultrasonic Evaluation of Particle Reinforced Aluminum Composite

  • 摘要: 用粉末冶金方法制备了两种碳化硅增强铝基复合材料, 其中制备两种复合材料所用的碳化硅颗粒和铝合金粉末的粒度比不同。分析了两种复合材料热压态和挤压态在径向和轴向的声速、衰减和草状回波的异同。结果表明, 利用超声波的声速、衰减和草状回波, 对粉末冶金方法制备的复合材料的微观组织进行无损表征是可行的。复合材料声速和草状回波可以用来反映复合材料各向异性, 其中草状回波还可以反映复合材料碳化硅颗粒的分布均匀性, 而超声波的衰减则对热挤压工艺比较敏感。
    Abstract: Two kinds of silicon carbide particulate reinforced aluminum composites in which the particle size ratio of silicon carbide to aluminum alloy power is different were fabricated by power metallurgy method. The ultrasonic velocity, attenuation and grass of the two kinds of composites were researched under hot pressed status and extruded status in radial and axial direction. The results indicated that the ultrasonic velocity, attenuation and grass can be used to evaluate the microstructure of composite fabricated by power metallurgy method nondestructively. The ultrasonic velocity and grass can reflect anisotropy of composites, and the grass can also reflect the distribution of silicon carbide particle. The ultrasonic attenuation is sensitive to hot extrusion.
