Ultrasonic Inspection of Alloyed Tungsten Bars

Abstract

Alloyed tungsten bars made from powdered metals that are compressed, sintered, and swagged can be ultrasonically inspected. Both longitudinal and shear waves were used, the latter being more sensitive. A frequency of 2.25 MHz proved best. One crack was found. The crack was equated to a standard.
