Bond strengths averaging 108, 400 psi were developed in joining precipitation-hardened beryllium -copper by diffusion techniques. This is in contrast with an average of 40,000 psi obtained by ordinary brazing techniques. The method of diffusion bonding studied in this program involved the use of molten alloys of silver and gold to fill discontinuities at the bond interfaces. These molten filler alloys are, in turn, completely, or in some instances partially diffused into the base metals, resulting in sound and continuous base metal-to-base metal bonds. Data were also developed on the effects of heating beryllium copper at 1550 and 1475 deg F on grain growth, elongation, reduction in area, and elastic modulus to determine its usefulness as a high-strength fabricated material for unusual applications.
