Indentation plastometry for material gradients and local transitions
When the material changes locally, the data should change locally too. Indentation plastometry makes point-by-point mechanical differences visible across graded materials, multimaterial systems and treated zones.

Why do gradients and transitions require local mechanical data?
Modern components increasingly combine different material states within one part. These can include multimaterial joints, graded structures, heat-treated zones, coated surfaces or other locally modified areas. In such systems, the decisive question is often not the global material value, but how the mechanical behaviour changes across the transition.
Conventional global testing can average out these differences. Indentation plastometry is valuable because it resolves them point by point and shows where the material state actually changes in a mechanically relevant way.
Which material systems benefit most from point-by-point characterisation?
Multimaterial joints
Graded structures
Heat-treated zones
Coated surfaces
Locally modified or transition-dominated areas
"i3D makes local transitions visible and usable for development, optimisation and validation."
How does indentation plastometry reveal local changes across a transition line?
By measuring point by point, R&D teams can visualise and compare local changes in strength-related properties directly along the relevant gradient or transition line. This makes mechanical differences visible where conventional global testing often averages them out.
Select the transition path: define where the local change is expected.
Measure along the line: place indentation points across the gradient or interface.
Evaluate each point: derive the local response from the measured imprint geometry.
Compare mechanically: identify weak zones, stable transitions or process-driven variation.
What becomes visible that global testing often averages out?
Local changes in strength, flow behaviour and transition stability can be compared directly across the part. This is especially helpful when engineers need to understand how process changes influence local performance and whether a graded concept delivers the intended mechanical profile.

Why is this useful for optimisation and validation?
The result is a clearer picture of local behaviour and a better basis for validating advanced material designs. Engineers can compare process effects more directly, understand whether local transitions are stable enough and support development decisions with better-resolved evidence.
