Abstract

The paper presents porosity evaluation of additive manufactured parts using ultrasonic nondestructive testing including scanning acoustic microscopy, ultrasonic velocity measurement, and ultrasonic attenuation coefficient measurement. Additive manufactured samples containing various levels of porosity were fabricated under various processing conditions. The scanning acoustic microscopy images clearly showed the porosity distribution and its quantitative amount in the samples. The ultrasonic velocity and ultrasonic attenuation coefficient results were related to the porosity results measured from the scanning acoustic microscopy. The increase in porosity caused the decrease in the material density, which resulted in the decrease of ultrasonic velocity and the increase of ultrasonic attenuation coefficient.
