In the August 2018 Journal of Failure Analysis and Prevention, EAG metallurgical experts Arun Kumar and Syavash Ensha describe their investigation into the causes of an aircraft crash. The article, “Liquid Metal Corrosion Fatigue (LMCF) Failure of Aircraft Engine Turbine Blades” details EAG’s metallurgical failure investigation, and how our scientists determined the reasons for the aircraft engine failure.
After detecting turbine blade failure, our experts discovered fatigue crack initiation, but what caused these cracks? Potential reasons included the age of the aircraft, poor maintenance, pilot error or a manufacturing issue. Read the article to learn how EAG’s metallurgical failure analysis experts discovered the reason for the accident.
EAG’s scientists and engineers use multiple analytical approaches to perform failure analysis for the aircraft, aerospace, transportation, construction and other industries.
Our metallurgical experts apply these approaches to detect fracture and failure modes, fatigue and slow crack growth mechanisms, contamination problems, wear failures, design/stress related failures, corrosion, embrittlement and more. Learn more about EAG’s metallurgical analysis services.
Rare earth magnets power some of today’s most advanced technologies. Part 3 of this series explores how the magnets are produced, challenges of maintaining purity at every step, and why precision analysis is essential for building a reliable supply chain.

Minerology was one of the earliest fields to benefit from X-ray Diffraction (XRD). Prior to XRD, minerals could only be identified by their external symmetry, shape, and color. XRD transformed mineral identification into an exact science, being perfect for characterizing crystalline materials by their internal structure, not just external appearance.
