                          METALLOGRAPHY LABORATORY

            Characterization of microstructure is a vital part of quality assurance and failure analysis.
            Although chemistry and mechanical properties may meet specific requirements, there are
            many situations in which an inferior microstructure can lead to corrosion, fatigue, or
            other stress-related problems in service.
            Our Metallography laboratory is staffed by highly experienced personnel and state-of-
            the-art equipment. We have the capability to produce digital images up to the limit of
            light-optical resolution. These images can be generated in “real time” in black and white
            or color, and transmitted electronically to the client.
            Experience is the cornerstone of our high quality metallographic sample preparation.
            Familiarity with the characteristics of metals and alloys of all types results in prepared
            surfaces free of artifacts and with good edge retention. Our knowledge of chemical and
            electrolytic etching provides the ability to reveal specific phases, metalworking features
            or the effects of thermal history. Among the typical structural phenomena we routinely
            evaluate are inclusion content, grain size measurement, weld defects, casting defects,
            mechanical working, stress corrosion cracking, decarburization, chemical segregation,
            prior austenite grain size measurement and other effects of heat treatment.

                                                FAILURE ANALYSIS

                      The PES/MCS Partnership
                      The relationship between PES and MCS Associates, Inc. (MCS) began in the 1980s. At
                      that time, the parent company of MCS, Metallurgical Consulting Services Ltd. (Canada)
                      was involved in several international failure investigations and PES provided mechanical
                      testing, NDE and laboratory support. It was largely as a result of this work that MCS was
                      founded in the US in 1991, and a natural consequence for collaboration between MCS
                      and PES to continue and grow. In 2001, MCS moved into offices on the PES premises in
                      Latrobe, PA and more complete business assimilation began. Although the two companies
                      retain individual identities, their operations are now fully integrated and together offer a
                      complete failure analysis service. With the metallurgical and testing facilities at PES, the
                      combined capabilities provide material selection, metallurgical analysis, heat treatment
                      optimization, R&D projects and litigation support.

                      Dr. Chris Bagnall
                      Dr. Bagnall, President of MCS Associates, Inc. and a Director of PES, has forty years
                      of professional experience in physical metallurgy. Early in his career, he worked at
                      The Welding Institute in the UK, then at The Boeing Co. in Seattle, WA, and later
                      at Westinghouse Advanced Energy Systems in Pittsburgh, PA. From 1993 to 2000, he
                      was employed at Concurrent Technologies Corporation, Johnstown, PA, with project
                      management responsibility. Dr. Bagnall has over 30 technical literature publications,
                      and is editor-in-chief of the international journal Materials Characterization. He is the
                      co-editor of two books and has been granted three US Patents. He is a Fellow of ASM
                      International, and is also a member of the International Metallographic Society.

                      Failure Analysis Experience
                      Experience with failure analysis has extended over 15 years, and has been a full-time
                      occupation since PES and MCS joined forces in 2001. Projects have included: forensic
                      investigation of damage to an afterburner in a municipal waste power generator; failures
                      to longwall mining components and mining chain; manufacturing problems with
                      microswitches, stainless steel, brass and bronze valves; defects in high voltage switch
                      components; fatigue damage in railcars and identification of defects in a wide variety of
                      cast, forged, rolled and drawn aluminum and specialty steel components. In addition,
                      PES/MCS has supported investigation of defects and failures in products and production
                      hardware associated with a wide variety of industries in the tri-state area of PA, VA and
                      OH. Consulting services have also extended to Canada, the UK and Europe.

                                             It is often necessary for practical or logistical reasons to perform metallographic studies

                                             metallography has developed significantly from its inception over 50 years ago. With
                                             the increasing and more stringent requirements demanded by safety regulations, the
                                             need for this service has grown. Inspections of large structures of all types, ranging from

                                             Field Surveillance Metallography (FSM) has not become widely recognized as an
                                             important technique for NDE. Its key attribute is that the surface preparation and
                                             subsequent metallographic examinations are nondestructive. FSM presents no hazard
                                             or risk to integrity or subsequent localized corrosion susceptibility of the structure.

                                              The advantages of FSM are that it is a powerful technique in its own right, and it can
                                              become an important contributor to a complete diagnostic analysis in combination
