INTERNAL FRICTION AND ULTRASONIC YIELD STRESS OF THE ALLOY 90 Ti 6 Al 4 V.

Abstract

The alloy 90Ti 6Al 4V has been suggested for use in the supersonic plane. It also has been used as a mechanical transformer for increasing the strain in a sample whose high amplitude and fatigue properties are to be studied. Hence it is important to determine its internal friction and modulus defect at both low amplitude and high amplitude vibration levels. (Author)
