Indentation Plastometry - i3D®

The principal of indentation plastometry according to the Imprint Test is a powerful solution for material testing. It allows the characterization of mechanical properties directly from indentation. This technology simplifies everyday processes and enables mechanical testing, which is not feasible with conventional methods. High-performance determination of yield strength (YS), tensile strength (UTS) and ductility.

The testing times are impressively short – only about 45 seconds per stress-strain curve, and that requires less effort for sample preparation compared to tensile testing. Additionally, the i3D features an optical 3D sensor capable of measuring surfaces with high precision, down to a few micrometers. i3D is a compact 2-in-1 solution that elevates your material testing to a new level.

Locally resolved testing of mechanical properties.

Fully automated characterization of strength fields.

Results within 45 seconds.

High repeatability and comparability to tensile testing.

Check multiple samples with, for example, more than 200 measurement points.

2-in-1 Solution: Measurement of Tensile Strength, Yield Strength, and Ductility + Optical 3D Measurements.

3 Stress-Strain Curves in 3:36 Minutes!

The unique feature of i3D® testing technology opens up new testing possibilities for your material testing. Research, develop, and produce faster than those who rely solely on traditional testing methods. The i3D® technology combines the cost-effective and flexible testing capabilities of hardness testing with the enhanced insights into mechanical properties from tensile testing, all in a single testing method.

Quickly test location-specific flow curves without the need to prepare a tensile specimen.
Suitable for a wide range of materials: aluminum, steel, structural steel, tempered steel, high-alloy steels, copper, nickel, magnesium, titanium – many metals can be tested.

Insight into Applications

Application #1: Multisample screening for the development of alloys with fast available data.

In the early stages of alloy development, quickly accessible data, including mechanical properties, is often very helpful. It accelerates the process of development through close iteration loops, where steps between adjusting parameters and getting data are accelerated exponentially. Within approx. 30 minutes, 30 plastic flow curves were measured.

Indentation plastometry high-throughput testing

Application #2: Weld seam examination. Testing of tensile strength, yield strength and ductility.

In the context of research work, weld joints were characterized for their mechanical properties in the base material, transition zone, heat-affected zone, and weld seam. Traditionally, the Vickers hardness test was used to measure local hardnesses with measurement points arranged in lines along the weld joint.

Technical Details:

Both variants serve the automated characterization of mechanical properties according to the indentation method specified in DIN SPEC 4864. Additionally, the i3D systems can also be used for optical 3D measurement.

ECO: Cost-effective solution optimized for laboratory use.
PRO: Additional capability for profile measurements (mapping) and fully automated testing of multiple samples (multisample screening).
