Why i3D® becomes technically strong for small geometries and fasteners
i3D® for component testing directly on small geometries, fasteners or local component areas: local yield strength Rᶦₚ₀,₂, tensile strength Rᶦₘ and further mechanical properties without a classical tensile specimen from the relevant zone.
Local values instead of hardness conversion
i3D® delivers local material properties related to Rᶦₚ₀,₂, Rᶦₘ, ductility and hardening instead of relying only on empirical hardness-strength correlations.
Low-damage and low-preparation
Testing remains small-area and component-near, without cutting, milling or transferring the relevant zone into a standardised tensile specimen.
Valuable for QA, failure analysis and development
Especially for small parts, fasteners, austenitic materials or local edge zones, the direct component statement is often technically more relevant than a global substitute specimen.
Component testing with i3D®
The i3D® method evaluates mechanical properties directly on small geometries, fasteners and real component zones without first having to transfer them into a classical tensile specimen.
From a materials-testing perspective, what counts is the local statement at the technically relevant location. Screws are a typical example, but not the only meaningful use case.
- directly on the fastener, small geometry or local component area
- suitable for small, complex and difficult-to-access geometries
- strong for component-near local material evaluation
Which properties are technically relevant
Yield strength Rᶦₚ₀,₂, tensile strength Rᶦₘ, ductility and hardening behaviour are the central results of the method.
For the materials-testing classification, it is important that these values do not come from a hardness conversion, but from the local indent and evaluation logic of the i3D® method.
- Rᶦₚ₀,₂ and Rᶦₘ directly from local i3D® evaluation
- additional statement on ductility and hardening
- stronger than purely empirical hardness-strength correlations
Why small parts and fasteners are demanding
Threads, notch radii, coatings, local forming zones and small cross-sections make small parts and fasteners particularly demanding for classical tensile specimens and standard samples.
That is exactly why local, component-near materials testing is technically valuable here: the relevant zone is evaluated directly instead of being approximated only by a global substitute route.
- suitable for thread root, shank, edge zone and locally treated areas
- relevant for small geometries and austenitic materials
- strong for fasteners, small parts and local problem zones
Practical relevance for QA and failure analysis
Quality assurance, material development and failure investigation are typical fields for this application because small parts and fasteners often need to be evaluated locally exactly there.
If failure starts in a small zone, a globalised testing statement is often not the technically best answer.
- relevant for QA, complaints, failure analysis and development
- local evaluation instead of only a global comparison specimen
- strong when component protection and real geometry are decisive
Contacts
Discuss component, zone and testing target directly with the right contact
If small geometry, fastener, coating or a local problem zone defines the material question, the testing route should fit geometry, material and target values directly.
