Phoenix Chapter of ASM - December Meeting

  • December 02, 2015
  • Heritage Room at the University Club - Arizona State University
  • Tempe , AZ , USA


Speaker Bio:

Mr. Jon Tirpak is currently Senior Program Manager for the SCRA Applied R&D Advanced Materials Division in Summerville, South Carolina. He is responsible for investigating, developing and implementing processes and technologies within the nation's foundry and forging industries, to reduce lead times and costs and to improve quality of complex metal shapes. He is the Executive Director of the Forging Industry Association – Department of Defense Manufacturing Consortium and Program Manager of the Defense Logistics Agency's PRO‐FAST Program.
Mr. Tirpak earned his BS in Metallurgical Engineering at Lafayette College in Easton, PA and his MS in Materials Engineering at the University of Dayton in Dayton, OH. He was commissioned by the US Air Force in 1982 as a 2nd Lieutenant, and researched the fatigue and fracture of cast aluminum alloys for airframes and performed failure analyses on various aerospace systems while assigned to the Air Force Materials Laboratory. His second tour within the Ballistic Missile Office involved integrating the Air Force's nuclear testing requirements which involved myriad materials and systems ultimately tested beneath the ground at the Nevada Test Site. In 1988, he departed the Air Force as a Captain, trading his blue uniform for green hiking togs to hike the entire Appalachian Trail from Georgia to Maine. After completing the trail and traveling extensively through Europe and the States, he resumed his materials engineering career with a position at Universal Technology Corporation in Dayton, OH and then to Aeroquip  Corporation in Ann Arbor, MI. Ultimately, he landed in Charleston,SC with SCRA Applied R&D managing programs and developing new business for the company.
Jon is a licensed metallurgical engineer in South Carolina and Fellow and past trustee of ASM International. Mr. Tirpak has chaired the New Products and Services Committee and the Federal Affairs Committee. He has served on many other communities and supported strategic planning for the Society. Presently he serves on the Finance and Investment Committees and is President of the Society.
Additive Manufacturing vs. Forging
Is direct digital manufacturing a threat to forging? That is the question this presentation will explore.Over the past decade many direct digital manufacturing or additive manufacturing technologies have been investigated with some being technicallyand commercially viable to make a shape. This presentation will identify the known current direct digital manufacturing technologies which compete with forging part manufacture and forging die manufacture. The presentation will identify the activities surrounding this technical community. For instance the ASTM F‐42 Committee was recently formed to standardize additive manufacturing technology with its first standard, ASTM F2792‐10. Several Additive Manufacturing (AM) technologies are available to produce metal parts. Whether or not these parts will compete with forgings remains to be seen. As fit‐check prototypes, perhaps yes; as fatigue resistant, fracture tolerant parts, perhaps no. It is advised that the forging industry continue to monitor AM sector to keep pace with these evolutionary or even revolutionary advances. Recommendations will be suggested to keep pace with these new technologies which could both benefit or cost the forging industry, depending upon one's perspective.
Project Vulcan: Historic, Heavy Hydraulic Forging Presses of the World
During World War II, the Allies quickly surmised that the German Luftwaffe benefitted from large magnesium forgings. In between WWI and WWII Germany turned to magnesium which was quite plentiful. To overcome the issues of high strain rate cracking of magnesium billet, the German industrial base moved from forging hammers to forging presses yielding high performance forgings. After WWII, the Allies raced across Europe to acquire technology, equipment and personnel unique to the large forgings. Ultimately another race occurred between the USSR and USA to design and build large forging presses. France entered the fray in the 1970s along with Weber Metals. The evolution of this important processing capability continues in the United States, Japan and China.
Metallurgist Gone Wild
In 1988, Jon Tirpak left the US Air Force and Thru Hike the Appalachian Trail from Georgia to Maine. This 6 month, 2137 mile trek recalibrated and reprioritized his life. This is a light, fun and entertaining presentation offered as a "bonus" presentation at chapter meetings.
