<< back to residual stress product overview

A proven performer in the field, laboratory and shop floor, the iXRD brings you an advanced system for your portable residual stress and retained austenite measurement needs. With our modular field stand approach, powerful software, easy to operate controls and our uniquely designed goniometers, we offer one of the most flexible and sophisticated instruments available in the world.

iXRD

Portable Residual Stress & Retained Austenite Measurement Systems

LIGHTWEIGHT, PORTABLE AND FAST

Proto’s iXRD models are built around a compact and portable  300W self-contained iXRD control unit. With integrated high-voltage supply,
x-ray tube cooling, motor control, system electronics and a  display panel for kV, mA and interlocks, it provides everything you need to run measurements. Additional safety features include  external  ports for interfacing to an enclosure or barrier,  and beacon lights for ‘shutter’ and ‘x-ray on’.

PROTO’S STATE-OF-THE-ART X-RAY DETECTORS

PROTO’s proprietary position sensitive scintillation detectors (PSSD) provide unsurpassed speed, stability and a wide 2θ range. Unlike other x-ray detectors, they do not deteriorate with exposure to x-rays. Our systems are equipped with two detectors, for accurate sheer stress determination. The detectors can be quickly positioned between Omega or Modified Side Inclination geometry. Available in standard 2θ range, extended 2θ range, and in a miniature package for our specialty miniature goniometers.

 

ACCURATE

At the core of every iXRD system is the powerful yet easy to use PROTO XRDWin 2.0 software. A comprehensive Windows®-based data collection and stress analysis package with features such as: linear and elliptical regression, Dolle-Hauk, and triaxial methods. Advanced peak fitting functions: parabolic, gaussian, pearson VII, cauchy, centroid, centered centroid, and mid-chord. Graphical display of peak  intensity, breadth, FWHM, and sin2ψ plots provides informative easy to read results. Software utilities for XEC determination,  principle stress, material removal, depth of penetration and retained austenite complete the package.

EASY & CONVENIENT TO USE

All of our iXRDs have features that make them easy and convenient to use. A high performance goniometer  maintains ASTM E915 accuracy in a low maintenance design. The manual focus pointer enables accurate positioning of the goniometer in complex geometries. The automated focus pointer provides convenient  focusing of large residual stress maps. A wide variety of x-ray beam apertures are available including: round 0.5, 1.0, 2.0, 3.0, 4.0 mm and rectangular 0.5x3, 1x3, 0.5x5, 1x5, 2x5 mm. High stress standards, zero stress powders & RA standards ensure accurate system results. Rapid positioning of the goniometer is accomplished with the easy-turn locking handles.

 

 

ADVANCED FEATURES

Portable Residual Stress Mapping (Patented) is available on all iXRD models, providing a  comprehensive picture of the residual stress state of your part. As the originators of residual stress mapping, PROTO is a leader in the field. Automated Retained Austenite as per ASTM E915 enables characterization of %RA in steels as low as 2%.  X-ray elastic constant determination (XEC) ensures automated residual stress measurement material calibration as per ASTM E1426.  X-ray Tube Cartridges allows for fast x-ray tube changes, while maintaining accurate system alignment.
