FAQ

Hardness testing calculates hardness by measuring the indentation mark left after unloading. In contrast, instrumented indentation testing continuously records the load-depth curve, allowing precise analysis of tensile properties, fracture toughness, and residual stress. This approach differs from conventional methods that infer tensile strength from hardness alone.

Residual stress can be measured up to 10 times the indentation depth.

Yes, customized fixtures can be made to accommodate various specimen shapes for accurate measurement.

Yes, measurements can be performed using fixtures specifically designed to fit the inner curvature.

Instrumented indentation testing typically takes up to 3 minutes.

Models AIS2100 and AIS3000 support a maximum load of 300 kgf, while lighter models (AIS3000 Compact, AIS3000 HD) support up to 120 kgf.

Depths of up to 150 μm for tensile and impact properties, up to 100 μm for fracture toughness, and at least 80 μm for residual stress under a load of 50–80 kgf.

Tensile property measurements require specimens of at least 10 x 10 x 2 mm. Our equipment accommodates a range of specimen sizes, including micro and nano scales.

Yes, a laser pointer on the fine-positioning system and a dovetail slider enables precise verification of the indentation location beforehand.

Connect the power and communication cables, hold the indenter holder to apply a load, and check if the load displays correctly in the program status window. Then confirm the displacement sensor function and verify it with a standard strength specimen.
