As an alumnus of the Metallurgical Engineering program (now Materials Science and Engineering department) at Iowa State University, CEO Larry Hanke has maintained a close relationship with the department and a keen interest in the education of future Materials Engineers. For almost 10 years, Larry has been invited back to campus once a year to present a lecture to junior and senior engineering students on various topics related to his 30-plus years of experience as a Consulting Engineer and Small Business owner. He lectured remotely last year, but was back on campus in March to present a lecture on Engineering Ethics for the Materials Engineering Professional Planning course and another on Fracture Analysis for a Failure Analysis course. He enjoys the questions and feedback from the students as he connects their textbook studies to his real world experiences.


ASM Failure Analysis Handbooks

posted March 2021

The newly revised ASM Handbook Volume 11 – Failure Analysis and Prevention has been released.  MEE Professional Engineers, Larry Hanke, Ryan Haase and Neal Hanke all contributed to this latest release.  Larry Hanke, P.E. co-authored two articles, Scanning Electron Microscopy for Failure Analysis and X-Ray Spectroscopy in Failure Analysis and was Division Editor for the section on Tools and Techniques in Failure Analysis. Ryan and Neal were editors and reviewers for multiple articles within the handbook including the Chemical Analysis section.

ASM Handbooks are a comprehensive multi-volume reference work covering every area of materials specialization. The staff at MEE recognizes that contributing to their professional organization benefits not just their personal career goals but the overall engineering and scientific community.

25 Years and Still Growing

posted January 2021


We are celebrating 25+ years at MEE.  Sometime in our first year we were given a small potted plant for our lobby.  Twenty six years, three facilities expansions and one re-potting later, MEE and the schefflera are going strong!



A tree grows in MEE.


MEE Intern Updates

posted October 2020

Reid Schur

Congratulations to former MEE intern, Reid Schur, on the publication of his paper Fractographic Analysis of Additvely Manufactured Ti6A14V by Electron Beam Melting: Effects of Powder Reuse in the June 2020 issue of the Journal of Failure Analysis and Prevention.
Reid was a senior in Mechanical Engineering at Washington University in St Louis when he interned with us in 2016. Currently he is a PhD candidate in the University of Washington Materials Science and Engineering Program.

Atte Kadoma

And, congratulations to 2017 MEE summer intern Atte Kadoma as she pursues her PhD in Engineering Sciences at Harvard John A. Paulson School of Engineering and Applied Sciences.  We first met Atte as a high school student in 2014 when she attended ASM Materials Camp. She kept in touch with us while attending Iowa State University where as a student in the Materials Science program she won a Goldwater Scholarship, the nation’s premier undergraduate scholarship in mathematics, natural sciences and engineering.


We always enjoy following the career paths of our summer interns especially when we see the paths have lead them to Materials Science Engineering research.

Sample preparation of steel tanks.


Sometimes projects involve samples or artifacts too large or too valuable to remove or cut for evaluation in MEE’s laboratories. In these cases, in situ evaluation is required.

For this project, MEE was asked to evaluate the functional integrity of large steel tanks that had been exposed to elevated temperatures from a fire. Associate Engineer, Henry Ahrenholtz, is seen here preparing a field metallographic specimen. The tank surface was prepared by grinding, polishing and chemical etching to reveal the microstructure of the tank material. A replica of the prepared surface was made and then examined using a portable microscope. A Materials Engineer’s specialized knowledge of the material properties and behavior under certain environmental conditions combined with metallographic expertise in the field provided valuable information for the client to aid in assessing any damage to the tanks caused by fire.



Thermal Fatigue Case Study

posted August 2020

A MEE case study on Thermal Fatigue has been added to our website. Our intent for these case studies is to provide you with a better understanding of what we do and how we approach typical projects at MEE. Each case study is taken from our files and has been edited to present a more casual writing style than our formal reports, but generally follows the structure of our reports and gives an overview of the findings and conclusions from an investigation.

Fracture features

While on our website, check out our Handbook of Analytical Methods for Materials (HAMM).  Topics in the handbook include the analytical methods available in our laboratory, as well as, other common materials characterization techniques we use to find solutions to our customers’ materials-related problems.


MEE staff, Larry Hanke, Dieter Scholz and Dan Grice recently presented webinars for ASM International. Both webinars are now available to view for free from the ASM International website. You will need to fill out a registration form before being directed to the webinar.

Fractography and Fracture Analysis: History and Development

A few comments from attendees of the Fractography and Fracture Analysis Webinar:

“A great overview of historic fractures. Well worth my attendance.”

“Please convey my sincere Congratulations to Dan & Larry for their superb professional presentation

“Highly systematic historical information regarding Fracture Analysis. Excellent user-friendly Presentation. Job Well Done”

Join MEE Engineers Dan Grice, P.E. and Larry Hanke P.E. next Tuesday, July 28th, for an ASM International webinar discussing the history of fractography and fracture analysis. Register today!

The study of fractures over the years has had an important role in materials engineering to improve product performance and reliability. This presentation will review the history of fractography, including the historical development of the science, changes in the analytical tools, and some historical case histories showing how fractography has been used over the past 100 years.
