POWERGEN International 2019

Paul Prevey
CEO, Director of Engineering
Lambda Technologies Group


Paul Prevéy holds a B.S. degree in Physics from Case Institute of Technology and has studied graduate level Material Science at the University of Cincinnati. Mr. Prevéy has designed and conducted numerous high and low cycle fatigue testing programs, including studies of the influence of various methods of machining and the residual stresses produced upon fatigue life. He has nearly 50 years of experience in x-ray diffraction residual stress measurement, conducting thousands of residual stress studies for power, aerospace, automotive and other applications. He has developed apparatus, procedures, and software for measuring residual stress, cold work and hardness produced by machining, shot peening and other surface treatments. Mr. Prevéy’s contributions to the area of residual stress measurement include original methods of determining x-ray elastic constants, methods of measuring plastic deformation, and mathematical procedures and software related to diffraction peak location. He has authored more nearly 40 publications related to residual stress and surface treatments and was elected a Fellow of the American Society for Metals for his contributions. Low Plasticity Burnishing (LPB®) was invented by Mr. Prevéy as a cost effective, production compatible alternative to laser shock peening based upon observations of how cold work and residual stress distributions determine fatigue performance. He holds seventeen US and additional foreign patents related to surface treatment.
