What is stress?
For metallurgical purpose the stress can be defined as the force experienced between any parts of the body of continuous material. Normally they are in a state of equilibrium and balanced internally.

What is Residual Stress?
The Stresses in the body, which are not in the state of equilibrium and are not balanced internally, is known as the residual Stress.

What is the effect of Residual Stress?
Residual Stress is the main cause of dimensional instability of the component. Hence they cause the premature failure of the component if not relieved or redistributed tor equilibrium.

How the stress level is evaluated & weather we can know that the stresses have been relieved?
Unfortunately there is no non-destructive technique available to indicate the Stress level. However, X ray detraction is the latest technique by which the effectiveness of the VSR is evaluated at CMTI, but again it is The destructive and the laboratory method. In Heat Treatment also no test is applied for the efficacy and the procedure is blindly applied.

How big jobs can be stress relieved by this process?
This method does not have any limitation by Size, shape or weight of the Job. Large or heavy jobs sue no problem but small jobs may need certain fixtures to be prepared to carry out the process.

How Reliable and effective VSR is?
VSR is equally reliable as TSR for achieving the dimensional stability of the metal. It has been tested and proved at CM-Ti. a Govt, recognized research institute, However it is not the direct replacement to thermal treatment for annealing, hardening or any other treatment where metallurgical changes are required in the metal.

Wether this process is approved under any code or standard?
In India CMTJ, Physical Laboratory and other institutions recognize the process. Many large organizations have also accepted and use the VSR technique. The Republic of China has standardised the code for "The selection of the technical parameters and requirements for vibrating stress relief process" The code is JB/T5926-9t. The VSR technique is widely used and accepted in most developed countries like USA, France, England japan, Russia, Germany, Bulgaria and now in India.

What should be the frequency and the duration of the vibration?
Every component has its own natural frequency. To maximize the effect The job should be vibrated to it's natural frequency and its harmonics. The typical duration can be 10 minutes at a given frequency. Most jobs get stabilized when treated for 15 minutes each at two different harmonic frequencies.

Whether the Job can be treated at site?
The VSR equipment is a portable machine and can be easily carried to the site. The job is to be isolated from the ground and then the process is applied at the site itself. Also almost all metals can be treated by VSR method except the precipitation hardened materials and severely cold-formed materials. We carry out the job at your site for VSR treatment provided the quantum permits.

Over the years, the usage of vibratory stress relieving process has become quite popular in the industry. It is latest non thermal technique of relieving the residual stresses of fabricated or cast components. Through this non thermal process, enormous amount of energy is saved which is not so through thermal stress relieving. These vibration stress relieving equipment are suitable for heavy fabrication shops and for the conventional stress relieving service providers.
