The aim of the study is to characterise hot-rolled and heat-treated plain-C steels (SAE 1020 and 1050) by ultrasonic velocity and attenuation measurements. Various heat treatment procedures were applied by changing the austenitisation temperature and the cooling rate to distinguish the affects of grain size and microstructural phases on ultrasonic properties. Velocities of both longitudinal and transversal waves were measured and backwall echo patterns were obtained for each specimen. The variations in the ultrasonic velocity and attenuation behaviour were discussed considering the microstructural investigations and hardness test results.
