Application of acoustic methods for the monitoring of products made of hard alloys

  • Published:
Materials Science Aims and scope

A system for the ultrasonic (US) control of large hard alloy articles developed in the Institute of Superhard Materials of the Ukrainian National Academy of Sciences is described. Ultrasonic control detects defects with a size from 0.3 mm in the sintering stage, which substantially reduced the number of damages in critical friction units. We investigate the influence of the structure on the sound velocity, modulus of elasticity, and damping properties of VK6 and VK8 hard alloys supplied by different producers.
