Forensic Engineering and Failure Analysis
Some of the most interesting and challenging projects at MEE are the forensic engineering cases. Forensic engineering is application of engineering principles to the investigation of incidents that have or may lead to litigation or other dispute resolution venues. Engineers at MEE practice specifically in the areas of forensic metallurgical engineering or forensic materials engineering. […]
Preparing Samples for Metallographic Examination
Not all of our projects come to us in small packages. How do we get that 7′ long, 6″ diameter steel tube or the 4′ diameter industrial fan under a microscope? Sample preparation often begins in our machine shop. The MEE shop is equipped with a variety of cut-off saws, a Bridgeport mill, plasma cutter, […]
Variable Pressure SEM vs Field Emission SEM
Two types of modern scanning electron microscopes provide the range of sampling handling and resolution needed for evaluating most samples – the variable pressure SEM (VPSEM) and the high-resolution field emission SEM (FESEM). At MEE, we offer SEM services with both types of microscopes to meet almost every challenge. The VPSEM is a workhorse for routine work, but magnification is not […]
Failure analysis case studies
Stress corrosion cracking in a chemical storage tank, hydrogen damage in a boiler tube, fatigue fracture in titanium sternal plates are just a few of the case studies on our website. They were specifically chosen to highlight the variety of projects we see in our laboratory and more importantly, demonstrate the thorough, analytical approach we take on all of […]
