Phased array ultrasonic testing of high temperatrue alloy fabricated by additive manufacturing

  • 摘要: 为了实现增材制造产品内部缺陷的有效检出,选取增材制造中激光选区熔化成型技术制造的GH3536合金为研究对象,测定了超声沿声束入射面的声速、衰减系数及主频偏移,然后通过优化聚焦法则实现了不同尺寸平底孔的有效检出,并对某典型结构件开展了实际检测,结果表明,相控阵超声检测能够实现材料内部缺陷的有效检出及定位。
    Abstract: In order to realize the effective detection of internal defects in additive manufactured products, the test sample of GH3536 alloy fabricated by selective laser melting (SLM) was selected, and data acquisition system was established to acquire velocity, attenuation coefficient and main frequency migration. Then side drilled holes with different size were tested by optimizing the focal law, and the typical structural parts was done. The results showed that, the internal defects in materials could be effectively detected and located by phased array ultrasonic testing.
