Abstract. The study investigated the high-temperature tensile behavior of Ti60 alloy at different temperatures (940"℃" to 1040"℃" ) and strain rates (0.1s-1 0.0005s-1). exhibited superplasticity with best deformation temperature ranging from 940"℃" 960"℃" . elongation samples decreased significantly over 980"℃" due growth grain size. In addition, influence diffusion bonding pressure on microstr...

An AZ41 magnesium alloy in the hot-rolled condition without further thermomechanical processing to modify its microstructure was investigated establish suitability for use within a superplastic forming process and optimum parameters. Formability assessed using elevated temperature tensile testing hot gas bulging, across range of strain rates (1×10?1?1×10?3 s?1) temperatures (350?450 °C). Circle...

Superplastic forming (SPF) is conducted in a heated, pressurized die where direct monitoring of critical SPF parameters is extremely difficult. Numerical models provide a critical means of tracking the forming process, allowing the applied gas pressure to be adjusted to maintain optimum SPF behavior throughout the forming process. This paper describes how the MARC finite element code was used t...
