Abstract

PURPOSE:To enable finding of a flaw in a cast steel product, especially a centrifugal casting material, by a method wherein an angle of refraction is selected so that ultrasonic wave from a probe transmits an object to be measured at an angle of approximately 45 deg. to a crystalizing direction. CONSTITUTION:In an ultrasonic made of an austenite system material, an angle of refraction of an ultrasonic beam is selected in consideration of a crystalizing direction of an object to be measured, and this permits obtaining of a high- precise flaw detecting result. Therefore, in case an ultrasonic longitudinal wave flow detection is made on an object to be measured made of a columnar crystal metal material, the angle of refraction is selected so that ultrasonic wave from a probe transmits the object to be measured at an angle of approximately 45 deg. to a crystalizing direction.
