Abstract. Superplastic forming is a sheet metal process that has found widespread use in the aerospace industry. It produces parts are free of residual stresses, dimensionally accurate, and with strains unobtainable using conventional methods. When combined diffusion bonding, phenomena where under similar processing conditions material involved will produce near flawless weld itself, variety re...

In this study, HA is superplastically embedded into Titanium substrate and the sample is subsequently deformed superplastically until 70% deformation degree. The former process is termed as superplastic embedment (SPE) while the later as superplastic deformation (SPD). After the SPE, HA is successfully embedded into the substrate, forming a layer with a thickness of about 249 nm. After the SPD ...

Superplastic deformation has a significant industrial application value due to the large elongation, which allows manufacturing parts with complex geometries but happens at elevated temperatures and low strain rates. Therefore, it requires alloys fine grain size whose grains tend grow processing temperatures. Second-phase particles can promote boundary pinning keep structure during superplastic...
