This application fits when yield strength, tensile strength and hardening must be understood not at room temperature but directly under elevated service temperatures.

Why i3D® becomes relevant for temperature-critical materials questions
i3D® for high-temperature testing and local material values at elevated temperatures: yield strength Rᶦₚ₀,₂, tensile strength Rᶦₘ and stress-strain curves under realistic thermal conditions.
Lower effort than hot-tensile routes
Initial developments show good agreement with classical hot tensile tests, with significantly lower effort for local questions.
Strong for temperature-critical zones
Component zones, weld areas and thermally highly loaded regions can be compared more selectively from a materials perspective than through global assumptions.
Relevant for high-performance applications
Aerospace, energy technology and high-performance mechanical engineering need such data when temperature strongly changes the mechanical statement.
High-temperature testing with i3D®
The high-temperature module extends i3D® to stress-strain curves at elevated temperatures.
This makes local material characterisation possible under realistic thermal conditions instead of answering the question only through global room-temperature data.
- local stress-strain curves at elevated temperature
- relevant for Rᶦₚ₀,₂, Rᶦₘ and temperature-dependent hardening
- strong for real thermal service conditions instead of reference states only
Local analysis at 400 °C and above
The i3D® method has already been extended to temperature ranges above 400 °C. Initial tests show good agreement with classical hot tensile tests.
Especially for temperature-loaded components and weld areas, this opens a new way to classify strength profiles locally and close to the component.
- initial temperature ranges above 400 °C already addressed
- comparability to classical hot tensile tests as technical reference
- suitable for local zones instead of only global high-temperature assumptions
Temperature-dependent material properties
With i3D®, temperature-related changes in yield strength, ductility and hardening can be captured with local resolution.
This is particularly relevant for understanding thermal load limits, local gradients and temperature-dependent safety margins in real component zones.
- local change of Rᶦₚ₀,₂ and Rᶦₘ under temperature
- classification of ductility and hardening behaviour
- important for creep-related and near-high-temperature questions
Development status and outlook
Further developments target temperature ranges above 1000 °C. This is a development status, not an already standardised serial function.
From a materials-testing perspective, exactly this distinction matters: already accessible temperature ranges deliver relevant added value today, while the expansion into extreme ranges opens further perspectives.
- suitable for aerospace, energy technology and high-performance mechanical engineering
- strong for development, laboratory work and technical classification
- further temperature expansion as a development field
Contacts
Discuss temperature window, material and local zone directly with the right contact
If service temperature, weld area or a thermally highly loaded component zone determines the result, the testing route should directly fit temperature, material and target values.
