Lambda Technologies Group specializes in the understanding, measurement, and control of residual stress.
Beneficial compressive residual stress applied appropriately mitigates failure mechanisms such as metal fatigue, stress corrosion cracking (SCC), pitting, fretting, and foreign object damage (FOD), among others.
Our expertise in both materials testing and life extension technologies allows us to provide you with a unique, total solutions approach to improve component life and performance.
We have been studying materials for over four decades, with more than 150 years of combined experience and well over 20,000 research programs.
We hold numerous U.S. and international patents about residual stress measurement and surface treatments to apply designed residual compression, including our renowned Low Plasticity Burnishing (LPB®) technique.
History of Lambda Technologies Group
Paul S. Prevéy, III and Professor B.D. Cullity, author of “Elements of X-Ray Diffraction,” start an accredited, independent laboratory specializing in X-ray diffraction and materials testing called Lambda Research, Inc.
Residual stress-based research at Lambda Research, Inc. leads to the invention of Low Plasticity Burnishing (LPB®).
A new division called Surface Enhancement Technologies, LLC (SET) is created to implement Lambda-developed surface treatment solutions in the business world.
Lambda Technologies Group is created to encompass both Lambda Research, Inc., a world-class X-ray testing facility, and SET, a multi-faceted engineering, and production enterprise for surface treatment solutions.
Lambda Technologies Group works around the world to offer complete surface treatment solutions, ground-breaking research and materials laboratory services.
