The residual stress diffractometer can be used to reveal residual stresses: in thermo-mechanically processed metals (e.g. products of rolling process):

The following material science physical phenomena can be studied in the residual stress experiment:
- Stress corrosion cracking due to extreme environments :
- Heat and pressure/stress (pressure pipes of power generators) - Corrosive environment and stress (pipelines, steel reinforcement in concrete) - Fatigue, crack growth and development in materials undergoing external loading or contact stress in structural components or load-bearing parts.
- Shape-memory alloys - these materials can return to their original shape after bending or deformation (e.g. vascular stents) and are used in medical and aerospace applications.
- In-situ plastic deformation experiment can reveal information on details of deformation mechanism of material (activation of slip systems, dynamic recrystallization, etc.). Frequently, this experiment is done using elevated temperatures and different rates of deformation.
- Creep, in spite of necessary time commitments, also can be studied, especially high temperature creep at constant load.
- Texture formation can be routinely studied using our Eulerian cradle
