Multiphase materials research

Studying of multiphase materials properties involves precise indenter positioning in the specified areas of the surface corresponding to the individual components. NanoScan-3D scanning nanohardness tester combines the functions of a scanning probe microscope and a hardness tester. Possibilities of the device allow obtaining three-dimensional surface topography image of a multiphase sample, and then specifying the measurement location with a connection to the resulting image.

Positioning accuracy of the indenter relative to the surface at measurements is about 100 nm in the XY plane.

Example: a D16 aluminum alloy sample (Fig. 1). Topography images of the same surface area before and after a series of measurements.
