Abstract : The vacuum brazing-gas quenching process or vacuum heating-gas quenching process is now a reliable method of joining materials, military and/or commercial hardware items. These hardware items include small munitions for chemicals, ordnance munitions, parts for jet engines, tanks, mortars, vehicle assemblies, and transportation mechanisms such as trucks and personnel carriers. The application of this process indicates quite readily that it is extremely broad, not limited to a small area or scope of endeavor. All that is lacking is the coordinated effort to put this process to work within DOD. The design capability exists for manufacturing, constructin, or building a multi-continuous chamber system. The process produces an ultrahigh value when related to quality - producibility is 99.99% for a helium leak standard of .000006 cc per second for 15 seconds at one atmospheric differential in pressure. The mechanical properties of the materials of this process are equal to and/or superior to those mechanical properties of the materials processed by conventional methods. The microstructure of each material or of the overall materials are slightly different but serves as an advantage to processing mechanisms for use and functional versatility.
