Biography
William John Arbegast is the youngest son of William John Arbegast Sr. and Gloria Florence Arbegast, nee Camps. They also had two daughters, Lynn Stover and Katie Patterson.
William John earned a bachelor's degree in metallurgical engineering from the Colorado School of Mines in Golden, Colorado . Since 1974, he worked as a metallurgist at Martin Mariett in Denver, Colorado , where he tested metals and non-metals for a launch vehicle and Space Shuttle, a space shuttle under development. There he became a major specialist in the field of production and test methods for aerospace components:
- heat treatment of metals ;
- welding ;
- chemical milling;
- non-destructive testing ;
- processing of materials.
Subsequently, he worked as head of the materials science department of the materials testing laboratory at Martin Mariett, focusing on testing various structural and fuel materials. There he first studied the formability and weldability of a new metastable beta-titanium alloy (Ti-15V-3Cr-3Al-3Sn), crack resistance and the growth of fatigue cracks in titanium castings (Ti-6Al-4v), aluminum-based composites with a metal matrix (6061 -17% SiC).
He later served as deputy head of research and technology for space rockets, worked in collaboration with the Department of Defense, NASA and Martin Mariett.
In 1990, he earned a degree in metallurgy and materials science from the Colorado School of Mines in Golden, Colorado.
Since 1996, he returned to the former Martin Mariett company, now called Lockheed Martin , where he developed a method of joining metals using rotational friction welding to create a launch rocket carrier (EELV). In the same place, he worked on the industrial application of friction welding for the manufacture of external fuel tanks for Space shuttles made of high-strength aluminum alloy 2219 and the very lightweight aluminum-lithium alloy AA2195, which could not be welded using conventional welding methods.
William John Arbegast founded and managed the South Dakota School of Mines and Technology National Science Foundation .
