Meet the Staff - Randall Moye

This week we will be introducing EPI Materials Testing Group's Lab supervisor, Randall Moye. Randall has worked for EPI Materials Testing Group for over 6 years, but has about 15 years experience in the testing and analysis industry.

Randall is a military veteren and knows how to keep the lab running on all cylinders. Along with making sure work is getting done right in our lab, he also runs many of EPI MTG's analyses including our X-ray diffraction analysis. This test identifies compounds of crystalline material.

At EPI MTG, Randall oversees our entire lab and is one of the main reasons why EPI MTG has been expanding its clientele and production since he was hired on. He is another valued person that makes EPI MTG one of the best testing and analysis labs in the world.

B611 Wear Testing

EPI Materials Testing group does custom wear testing and three standardized wear tests for their clients, ASTM G65, G105, and B611.

The B611 test is an ASTM 'Standard Test Method for Abrasive Wear Resistance of Cemented Carbides'. The test wheel is made of AISI 1020 steel and has an OD of between 6.5" and 6.65".

The B611 test is used mainly for what it is intended, Cemented Carbides. It is also used as a research method to test the differences between different carbide compositions. This test runs in a slurry mixture making it very abrasive as compared to the G65 testing.

Along with these test we have talked about for the last few weeks EPI Materials Testing also does custom testing for clients who are doing research and development of new and older carbides.
