Ultrasonic stress relief

Introduction to ultrasonic stress relief

This section describes a variety of processes and effects related to ultrasonic stress relief for materials processing, replacing conventional heat-treatment processes which can be energy-intensive and / or impractical for large components. Some of the beneficial effects include:

  • Fast stress relief
  • Fatigue life extension
  • Accelerated aging and material-properties stabilization
  • Early detection of mechanical defects
  • Ability to treat components too large for any oven
  • Algae, Barnacles & Biofilm removal
  • Surface implantation of different particles and powders
  • Quenching and hardening
  • Improved surface coating
  • Coatings over welds to extend fatigue life
  • Accelerated neutralization of free radicals
  • Polymerization
  • De-polymerization Degassing and de-bubbling. Improved alloying and casting
  • Production of homogenous biocompatible alloys. Facilitated implantation and/or penetration
  • Enhanced cleaning and sterilization
  • Deep capillary cleaning

One or more of a variety of treatment methods may be used depending on the required effects and equipment limitations, eg. size and access. The methods used include:

  • MMM ultrasonic (screw-on / clamp-on)
  • Ultrasonic bath
  • Ultrasonic vapor chamber
  • Ultrasonic sand blasting
  • Ultrasonic chemical etching,
  • Shot and ball peening

Many applications will be described in detail in the following pages, including:

  • Ultrasonic stress relief
  • Fatigue life testing
  • Preventive maintenance
  • Real-time cleaning of deposits and scaling
  • Cleaning, descaling, cutting, liquid-metals agitation
  • Ultrasonic vibrothermography
  • Ultrasonic dry cleaning
  • Optimized surface coating
