Tomographic Determination of Temperature Distribution in Billets (RESEARCH NOTES)


, Shahid Bahonar University of Kerman


The principles of Ultrasonic Computed Tomography (UCT) are reviewed in this paper. The UCT is a powerful nondestructive technique in medicine and recently in industry to reveal an image of a slice of an object or body. The advantage of UCT over other conventional techniques in imaging is that a computed tomogram yields quantitative information about the section of interest. Experimental works on obtaining a tomogram of the temperature distribution in the mid-section of a block of an aluminum alloy utilizing the available simple equipment are carried out. A discussion of the analysis and results is presented. Certain modifications are also suggested to improve the accuracy and reproducibility of the results. A
