Diffusion Welding of Wrought Beryllium.
Abstract
The objective of the study was to investigate the role of the microalloying elements on the diffusion welding of beryllium and to relate the welding behavior to variations in beryllium oxide content. Diffusion welding of beryllium was shown to involve the precipitation of intermetallic compounds of the joint interface. The rate of precipitation was temperature related, but was also related by the Be0, iron and aluminum contents singularly or collectively. It was also demonstrated that the strength and ductility of beryllium sheet containing 0.97% Be0 can be altered by the diffusion welding temperature, quench rate and additional post weld thermal cycles. It was concluded that compounds formed between the beryllium and the microalloying elements play a significant role in the diffusion welding process and in the strength and ductility of wrought beryllium.
