Our laboratory and industrial testing residual stress XRD powerhouse, the LXRD system is designed for heavy-duty, around-the-clock operation. Extremely fast, accurate, and reliable, the LXRD offers the highest return on investment in the industry. Measurements can be performed in as little as a minute.

 

The LXRD is available with standard or oversized enclosures for large part capacity. Flexible instrument options and available residual stress mapping make the LXRD a proven leader in high-powered residual stress and retained austenite measurement systems.

 

Our high-performing LXRD Standard small enclosure system, designed with compactness in mind, can fit through a single door. This system is perfect for measuring smaller parts and samples up to 30 cm.

This state-of-the-art instrument is available in a cost-effective bare enclosure configuration or upgraded with numerous options, including a manual XY-positioning stage, phi rotation stage (automated triaxial measurement), fully automated 300×200-mm-travel XY residual stress mapping stage, and % retained austenite measurement capabilities. The radiation-proof enclosure, automated 400 mm z-axis, MG2000 1200 W high-power goniometer, fully integrated chiller, and levelling pads with wheels provide performance and flexibility in a compact package.

EASY AND CONVENIENT TO USE

All of our LXRDs have features that make them easy and convenient to use. The high-performance goniometers maintain ASTM E915 accuracy in low-maintenance designs. The manual focusing pointer enables accurate positioning of the goniometer in complex geometries, while the automated focusing pointer allows convenient focusing of large residual stress maps. A wide variety of x-ray beam apertures are available, including round 0.2, 0.5, 1.0, 2.0, 3.0, and 4.0 mm options and rectangular 0.5×3, 1×3, 0.5×5, 1×5, and 2×5 mm options. High stress standards, zero stress powders, and RA standards ensure accurate results. Integrated cooling makes for self-contained instruments.

ADVANCED FEATURES

Residual stress mapping is available on all LXRD 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 1%. X-ray elastic constant (XEC) determination ensures automated residual stress measurement material calibration as per ASTM E1426. Pole figures created using the LXRD rotary stages can be used for preferred orientation analysis, single-crystal orientation, and single-crystal stress measurement.
