ESi's lab and industrial services team provides a complete scope of materials testing services, including chemical composition of metallics, mechanical testing, metallurgical analysis, radiography, specialized test design, and performance.
Our labs and testing facilities are the data conduit, not only to our in-house consultants, but also to our industrial customers. Frequently, our clients have their own in-house engineers and managers that need to know whether their incoming materials meet specifications.
Utilizing ﬁre-damaged components as well as virgin aluminum alloy 2024-T3, ESi developed a clear correlation between electrical conductivity and mechanical properties of damaged and as-speciﬁed material. ESi’s nondestructive metallurgical evaluation of the Beechcraft model T-34B front CT spar conﬁrmed that its mechanical properties were not aﬀected by the localized ﬁre.
Broken gear teeth from the clutch mechanism of a marine sterndrive unit were analyzed and determined to be a result of long-term wear leading to fatigue cracking of the gear teeth.
An ESi investigation combines metallurgical, mechanical and chemical analysis to determine the cause of a rifle accident. ESi ultimately contributes the powder analysis to the National Center for Forensic Science Smokeless Powders Database.
Localized corrosion to carbon steel boiler tubes was the result of localized boiling and scouring of protective oxides on the tube wall. Metallurgical and chemical analysis revealed no indication of stress-induced failure.
Using a combination of chemical and metallurgical principles, ESi determined that stainless steel kitchen components could be restored to their pristine state.
The customer was delighted in the confirmation of their initial response to their European customer--that the parts met the drawing requirements for roughness and surface flaws and were structurally sound for their intended, albeit very rough, use in grinding railroad rail profiles.
ESi’s extensive aviation experience includes deep expertise in high temperature turbine blade superalloys. We routinely diagnose blade issues such as metallic creep, fatigue cracking, and sulfidation corrosion.
The results of ESi’s investigation were used to recommend and substantiate to the USAF Technical Airworthiness Authority (TAA) a return to pressurized flight without altitude restrictions.
Based on the results and findings of this multi-component failure analysis, the client was able to remedy the problems with the new machinery design by addressing the weld defect and successfully launch the new product line.
ESi has been performing field and physical testing of composite railroad ties to refine industry specifications on mechanical and thermal performance.
An ESi investigation proving manufacturer defect prior to transport damage results in a reduced claim settlement for the client.
Overview: Contamination—we've all seen it in some form. In this presentation, we will explore various methods of identifying contaminants and their sources.
When components fracture, fatigue is often the reason. Ron Parrington walks you through the definition and types of fatigue, how to design and test for fatigue, and common fractographic features in fatigue failures.
ESi launches a new Chemistry sub-practice within our Materials practice. Sr. Consultant Jason Babcock, Ph.D. has been appointed to lead this new team, which brings together premier analytical and forensic chemistry expertise.
ESi's expertise spans dozens of industries and specializations organized across several practice groups, each staffed by dozens of in-house experts with the technical knowledge, hands-on expertise, and courtroom experience required to execute projects for and with our clients from start to finish.Find an Expert Contact Us
