Opis:
The hydro-mechanical drawing combines conventional deep drawing and sheet hydroforming and is widely used in the automotive industry. In this study, we designed and fabricated an indigenous experimental set-up that is low cost, low weight and portable. This study investigated the deformation of sheet metals into hemispherical cup-shaped parts made of different materials, viz., aluminium 8011 alloys, copper C12200 and steel EN10130 alloys. The initial thickness of sheet metal was 0.4 mm, the most common thickness range used in automotive applications. The deformation behaviour in terms of dome height has been measured by varying the pressure of the fluids. Aluminium 8011 alloy sheets showed a maximum dome height of 11.46 mm at a pressure of 1.47 MPa with no rupture. Steel EN10130 sheets had a maximum dome height of 10.89 mm at a pressure of 9.31 MPa. It was concluded that the behaviours of materials are different in the hydro-mechanical drawing process than in mechanical tests. Copper C12200 sheet showed superior formability with a maximum dome height of 18.91 mm at a pressure of 7.06 MPa than other materials without fracture.

Opis:
Vacoflux-49 (Fe-49% Co-49% V-2%) is used in torque, sonar and gyroscopic sensors applications due to excellent magnetic properties (high saturation magnetisation, low coercivity and high Curie temperature). In this study, the shape, size and characteristics of different thermal zones and the microstructural evolution during electron beam melting and welding of Vacoflux-49 material are studied. The experimental studies on melting have been carried out with under-focussed, focussed and over focussed electron beam. In the case of the under-focussed and over-focused beam, no evaporated zone is found. In the case of focussed beam, a shallow conical-shaped evaporated zone, a choked funnel-shaped fusion zone, a conical shaped partially melted zone and the heat-affected zone are observed. The solidified melt pool in terms of shape, size and microstructure of different zones are investigated for the focussed beam. The grains in the fusion zone appear wavy having crest and trough. The fusion zone microstructure also shows the formation of solidification rings. From the electron beam welding experiments performed for joining two Vacoflux-49 plates (continuous welding), it is found that the weldment shape is similar to the spot melting and re-solidification experiments. The grain growth in different zones in the welding sample is also examined.
