... parameters such as temperature and pressure have significant effects on part accuracy, quality and desired characteristics. The purpose of this paper is to present a numerical and experimental investigation of process parameters in superplastic free bulge forming. Design/methodology/approach...

...Shafiqur Rehman; S.A. Khan Purpose This paper aims to present the results of an experimental investigation carried out to control the base pressure in a suddenly expanded axi‐symmetric passage. Design/methodology/approach Four micro‐jets of 1 mm orifice diameter located at 90° interval along...

...S.A. Khan; E. Rathakrishnan Purpose This paper presents an experimental investigation to study the effectiveness of micro jets under the influence of Over, Under, and Correct expansion to control the base pressure in suddenly expanded axi‐symmetric ducts. Design/methodology/approach Four micro...

... The seamless pressure vessels can be made from almost all metals: however,the customers prefer high strength, stainless high-grade steel, titanium or aluminium. The material is being cold hardened by flowforming, giving it a higher strength. Using this technique, it is possible to reduce...
