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.

Materials Science Camp

posted July 2019

This was MEE’s 13th year as a sponsor of ASM International Materials Science Camp for high school students. ASM Materials Camp utilizes hands-on learning principles of applied math and science for a truly unique, team-based problem solving experience that explores materials science and engineering principles.

The students are assigned a failure analysis project on the first day of camp and spend a day in the laboratories at MEE examining their samples and gathering data.  They prepare their samples in the metallographic lab, view the microstructure using SEM and metallographic microscopes and perform Rockwell hardness tests all under the direction of  industry and education based Materials Mentors.

Three MEE staff, Larry Hanke, Kurt Schenk and Neal Hanke, were camp mentors for the entire week of camp.

Consulting ASM Handbooks

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.

MEE just added a new potentiostat/galvanostat instrument to our busy corrosion laboratory. The VersaSTAT 4 is an advanced and versatile instrument expanding on our electrochemical corrosion testing capabilities.

Electrochemical corrosion experiments can provide a variety of data related to the pitting, crevice corrosion, and passivation behavior for specific sample/solution combinations. These data are useful in selecting materials and/or determining how manufacturing processes affect corrosion properties.

Read more about corrosion testing on our website and in our online Handbook of Analytical Methods for Materials.  Or you may call and talk to one of our technical staff for typical applications and sample requirements.

We weren’t familiar with the Minneapolis city flag until just recently, but were pleasantly surprised to see one of the symbols on it is a microscope. That seems fitting to us! Microscopes are one of the most important tools we use at MEE to provide our clients in the medical device, industrial and electronics industries with high-quality materials characterization for their advanced materials and critical components.

MEE has three scanning electron microscopes (and a new one coming this summer) and a light microscopy laboratory equipped with a variety of light microscopes with magnifications ranging from 5X to 2,400X.

There is a small contingent of Minneapolis citizens advocating for an update of the flag. We would hate to see the microscope image go away but either way, MEE will always be flying the microscopy banner.

Medical device development calls for innovation, precision and critical thinking – MEE matches your requirements with advanced materials characterization, analytical methods and experienced and informed materials strategies.

Look for us in the exhibit hall of the upcoming MD&M event November 8-9 at the Minneapolis Convention Center.  Materials Evaluation and Engineering staff will be there to meet and greet and answer any questions you might have about our services.

We will be at Booth #1304 (first booth if you enter through the central doors of the exhibit hall.)

New Engineer Added to MEE Staff

Jason Larson (2)

 

Welcome Jason Larson.

Jason, who joined the MEE staff as a Senior Engineer, brings with him 10+ years of experience in failure analysis laboratories, supporting the electronics and medical device industries. His degree in computer engineering combined with project experience analyzing failure modes in microelectronic components expands on MEE’s capabilities and range of engineering expertise.

 

 

Filed under: About MEE,

Welcome to our summer intern, Atte Kadoma. Atte just completed her freshman year at Iowa State University where she is working towards a degree in Materials Engineering. We first met Atte in 2014 when she attended ASM-MN Materials Camp as a high school student.  MEE is a corporate  sponsor of Materials Camp and the students spend a day here getting hands-on experience in a materials testing laboratory.  We even found a photo in the Materials Camp photo archives of Atte at the Rockwell hardness tester!

Atte has long been interested in pursuing an engineering degree but said her experience at Materials Camp definitely influenced her decision to choose materials science engineering as her major. She has expressed a particular interest in failure analysis.

We were very pleased to be able to offer Atte an internship this summer and look forward to working with her.
