INVESTIGATION OF RESONANT BEAM AND ULTRASONIC METHODS FOR THE EVALUATION OF SINTERED POWDER STEEL COMPACTS

Abstract

Results of an investigation designed to determine the practicabillty of evaluating the mechanical properties of sintered steel powder compacts by ultrasonic and mechanical resonance technique are described. The yield and tensile strengths of sintered prealloyed steel are correlated with sintered density, resonant frequency, sonic and ultrasonic velocity, as well as C-scan ultrasonic transmission recordings. The correlations that have been established demonstrate the effectiveness of sonic and ultrasonic methods for the nondestructive evaluation of sintered powder metals. The experimental procedures are described and the capabilities and limitations of each technique are discussed.
