Title

INVESTIGATION OF RESIDUAL STRESSES IN STRESS-RELIEVED SAMPLES BY HEAT TREATMENT AND ULTRASONIC METHODS USING HOLE-DRILLING METHOD

Pages

  273-278

Abstract

RESIDUAL STRESS is stress that remains in the body, such as some specific operations like welding, and is available when body is not under external loads. Different methods are available for RESIDUAL STRESS relieved in any welded samples. In this research, samples one, two and three have been prepared and welded. Stress of samples one and two have been relieved using heat treatment method and ultrasonic method, respectively. Also, no operation has been taken on the sample three. For different amounts of RESIDUAL STRESS of each sample, HOLE DRILLING METHOD was used and amount of RESIDUAL STRESS in welding heat affected area of each sample was determined. Results show that RESIDUAL STRESS in ultrasonic method is less than heat treatment method. To validate the results the X-RAY DIFFRACTION METHOD was used and results of this method show that in the sample with ultrasonic stress, stress relief had no peak at 2θ angles, but for sample with heat treatment stress releif had a peak at 137o, which shows some RESIDUAL STRESS.
