Metallurgy for the Non-metallurgist – Association of Firearms and Tool Mark Examiners
Dana J. Medlin, Ph.D., P.E., FASM of EAG Laboratories and Frederick E. Schmidt, Ph.D., P.E. will present the general aspects of firearms metallurgy for firearms and ammunition producers, as part of the annual training seminar for The Association of Firearm and Tool Mark Examiners on May 19, 2017 in Denver, Colorado.
The topics will include a summary of the physical and mechanical test methods used in the metallurgical laboratory for understanding firearm and ammunition properties. Other topics include metal corrosion, metal surface finishing and heat treatment methods. This full day course will include:
- A brief history of metals from the first development of metals for use as weapons thousands of years ago to the modern era will be given.
- A basic explanation of the distinctive physical and mechanical properties that make metals exceptional materials for firearm and ammunition applications.
- A comprehensive review of the national and international alloy designation systems used to identify metals.
- A general overview of basic physical metallurgy theory and applying these theories to appropriate alloy manufacturing and heat treatment methods.
- Explain how metals are formed into engineering components with specific reference to firearms and ammunitions.
- Heat treatment terminology, methods and best practices for firearm components.
- A basic overview of physical and mechanical test methods to determine critical properties of metals, as well as a discussion concerning typical standard test methods for firearms metallurgy.
- Explain the basis for the selection process of different alloys for specific applications.
- Review the fundamentals of metal corrosion, corrosive environments, why different metals respond differently to corrosion, and controlling/minimizing corrosion damage.
- Explain typical metal surface finishing techniques for firearms, the processes involved and the performance attributes.
