- Ducom Automated Indentation Tester offers an in-situ, non destructive method of determination of aging related changes in material properties of components.
- Advanced design with software based operation, data acquisition and analysis
- Adapters for field testing of pipes and bench testing of small samples.
- Ball impression is less than a mm in diameter, hence nearly a nondestructive test.
- Ideally suited for weld zone and HAZ as testing is localized.
- Strain or Stress controlled loading and unloading curve.
- Correction factor for indentation area to account pile-up/sink-in.
- One-click surface integrity assessment for time saving and comfort.
- Integrated Surface Cleaner
- Adaptor – Chain Strap
- Adaptor – Magnetic Clamp
- Power Pack
- Trolley and packing case

Change in mechanical properties of materials during service reveals health and integrity of components. In case of critical component in service, it is not always possible to extract standard test specimen for laboratory test. In this situation, in-situ nondestructive testing on in service components is required and the Ducom Automated Macro Indentation Tester is the instrument of choice in such cases. The Automated Macro Indentation Tester (AMIT) is designed and manufactured exclusively by Ducom Instruments and is distributed solely by a network of Ducoms’ authorized distributors.
The Automated Macro Indentation Tester works on recording of load-displacement characteristic of a ball indenter during loading and unloading of sample under test. This information with inputs like material data, Meyer’s constant and correction factors is processed to estimate following properties:
- Yield stress
- Yield ratio
- Tensile strength
- Strain hardening constant
- Fracture toughness
An indenter of desired ball radius can be selected depending on nature of material. When the test site is rough or covered with deposits, rust or paint, the target area can be cleaned before test with a grinder attachment. The Automated Macro Indentation Tester (AMIT) is software controlled.
