Forming of tee parts by a process that combines diffusion welding and pneumothermal forming in the superplastic regime

Abstract

An alternative method is described for making tees. The article discusses the main stages in the advanced method, which combines diffusion welding and pneumothermal forming in the superplastic regime. The process of superplastic pneumothermal forming is modeled and calculated results are reported. In the method, pneumothermal forming is preceded by diffusion welding. © 2013 Springer Science+Business Media New York.
