Failure Analysis Seminar

posted August 2019

Senior Materials Engineer, Dan Grice, P.E., presented a two day seminar on Fractography and Failure Analysis at the office of one of our industrial customers.  The seminar covered technical information on fracture mechanisms and analysis through characterization of the macroscopic and microscopic fracture features.  Dan’s presentation included multiple case studies to provide a practical understanding of the analytical methods and laboratory tools a materials engineer uses in the failure analysis process.

Materials Evaluation and Engineering, Inc.  is pleased to announce that Henry Ahrenholtz has joined our staff as an Associate Engineer. We hired Henry to support MEE’s  busy materials characterization laboratory.  He has rapidly become skilled in nondestructive testing methods, visual examination, metallographic sample preparation, microstructure examination, and mechanical testing. He has already been involved in two large industrial projects assisting senior engineering staff on the job site and in the laboratory.  We are confident that Henry will be a strong asset to the MEE team.

Henry is from Minnetonka Minnesota and attended Iowa State University, graduating in 2018 with a degree in Materials Engineering with a specialization in polymers. When not at work in the Metallography Lab, Henry enjoys rock climbing and cycling.

Larry Hanke,P.E. and Neal Hanke, P.E. will be presenting a talk on the role of the metallurgical engineer in fire investigations at an October 12 educational seminar in Lakeville, MN. The seminar is directed at fire investigators, insurance professionals and lawyers to highlight the importance of laboratory testing  of artifacts in a successful investigation.

Larry and Neal will provide their expertise on:

  1. A fundamental understanding of how structural and electrical materials behave at elevated temperatures.
  2. How material behaves under stress.
  3. How to evaluate component failures that may contribute to fire and explosion
  4. A better understanding of how to identify electrical arcing
  5. How anomalous material behavior can lead to incorrect conclusions about the conditions during a fire

Last Thursday we hosted thirty high school students at MEE  as part of a week-long Materials Science Camp sponsored by the MN Chapter of ASM International.  Under the direction of  industry and academic based “Materials Mentors”, students learned about the process of running a failure analysis investigation. MEE provided a space for the students to get hands on experience with sample preparation, Rockwell hardness testing, light microscopy and scanning electron microscopy.

 

 

Three of our staff, Larry Hanke, Kurt Schenk and Neal Hanke, were  camp mentors. This was MEE’s twelfth year sponsoring the camp.

Senior Scientist, Dieter Scholz and Materials Engineer, Neal Hanke will be speaking at the Minnesota chapter of ASM 2018 seminar in Brooklyn Park, MN on February 28. The Materials Characterization Seminar is an opportunity to learn about the most recent developments in advanced characterization techniques and their practical applications.

Dieter will be speaking on Broad Beam Ion Milling in Sample Preparation and Neal’s presentation is on the Determination of Nitinol Transformation Temperatures by the Bend and Free Recovery Method.

MEE Senior Materials Engineer, Dan Grice, was just named to the Board of Directors for the Failure Analysis Society  (FAS) of ASM International.  Dan will be acting as liaison to the FAS Membership Committee. Among his goals will be to develop programs within FAS to increase membership and improve services for the emerging professionals demographic.

“The Failure Analysis Society is the newest affiliate society from ASM International. Founded in 2016, this society is dedicated to advancing the important role failure analysis plays in the materials science industry. We aim to promote more safe, reliable products by study of the many ways in which failures occur and to educate the larger engineering, manufacturing, and user communities regarding our findings.”

 

Testing to Industry Standards

posted August 2016

We added a new page to our website, Testing to Industry Standards. Select ASTM test methods we have experience with are listed. The list is by no means all inclusive. If you don’t see the test method you require, contact us. We will work with you to interpret test methods and identify those tests we can perform or assist in identifying the appropriate test method for your particular project. We can even design custom test programs when required.

The National Society of Professional Engineers (NSPE) has proclaimed August 3rd as Professional Engineers Day. Here’s to the PE’s on staff at MEE; Larry Hanke, Richard Kielty, Ryan Haase and Dan Grice.

From the NSPE:

“For engineers, licensure is required in order to submit plans to a public authority for approval, to work as a consultant, or to be in responsible charge of engineering work. It is a means of ensuring standards of professional competency through a rigorous combination of education, experience, and examination.”

For those of you interested in history, the NSPE  published an article a few years ago on the history of professional engineer licensing that is worth a read.

 

 

 

Failure Analysis Society

posted July 2016

“ASM International (ASM), the world’s largest association of metals-focused materials professionals, has launched a new affiliate society, the Failure Analysis Society (FAS). The society is dedicated to advancing the important role failure analysis plays in the materials science industry.”

Congratulations to MEE Materials Science Engineers Larry Hanke, Ryan Haase, and Dan Grice who have been selected as founding members of the Society.

What are the benefits to working with an engineer or scientist who is actively involved in their professional society?  You know you are working with someone who has an interest in sustaining and advancing their field, places a high level of importance on professionalism and ethics and is keeping up-to-date on trends and best practices.
