X-Raybot

The X-Raybot is an X-ray diffractometer developed by MRX Mesures Rayons X for residual stress analysis.

It is mounted on a 6-axis robot, uses a laser triangulation system for accurate positioning (to EN 15305-2008) and is furnished with the latest generation (air-cooled) X-Ray tube and Si solid state detector.

The robot is portable for on-site use (no cabinet required) as well as in the laboratory, and benefits from the powerful StressDiff data analysis software supplied.

The unique selling point of the system is its capability to account for the local curvature of surfaces where the surface normal is non-vertical.

Robot Options

The X-Raybot goniometer can be mounted on 3 sizes of robot:

• A large arm (150 cm) for industrial use

• A medium length arm (120 cm) for lab use

• A small arm (80 cm) for portable use

The large robot requires a heavy duty mounting frame, whereas the medium and small robots can be mounted on either a fixed frame for laboratory use or a portable stand for “in-situ” use.

Retained Austenite

• Diffraction diagram acquired in less than 1 minute

• Full fitting of the diffraction pattern

• Account for curvature of the diffraction rings

• Account for existing carbides and nitrides

2D X-Ray diffractometer

• Multiple exposure technique to avoid significant systematic errors existing in the classical cosine α method

• Complete stress tensor components evaluated in less than 1 minute

• Robust error bars evaluation according to the Guide of Uncertainties in Measurements (GUM)

• The diffraction rings can be described by more than 300 polar diffraction diagram cuts

• Each diffraction pattern is fully fitted through a non-linear best fit method that permits to account for overlapped peaks
