Effect of Explosion Bulge Test Parameters on the Measurement of Deformation Resistance for Steel
نویسندگان
چکیده
This paper investigates the effects of varying some of the explosion bulge test conditions on assessment of the plate deformation resistance (bulge depth and plate thinning), focusing on four parameters: (a) use of cardboard wrapping to provide thermal insulation for the test plate prior to blasting (b) changing the means of supporting the charge above the plate from a cardboard box enclosure to a suspended stocking, (c) effect of testing temperature, and (d) the effect of crack starter weld beads on plate deformation. Of the four parameters, it was found that the use of a cardboard box enclosure provides measurably different outcomes compared to a charge suspended from the ceiling by a stocking.

Nickel-based Superalloy Layer Deposited on AISI H13 Hot Tool Steel Base Metal Using Explosion Cladding process
An experimental test was carried out to explosively clad solution annealed Inconel 718 superalloy on quench-tempered AISI H13 hot tool steel. A wavy with vortices interface geometry was obtained from this experiment. A gradual change in the wavelength along the direction of welding was observed which was due to a change in the impact angle, following the plate contacts. In this paper, the exper...

متن کاملThe Effect of Welding Parameters on the Room and High Temperature Tribological Behavior of the Weld Overlaid Die
As an important problem in forging factories, dies are destroyed because of high wear rate, plastic deformation and thermal and mechanical fatigue at high temperatures. This paper is an investigation into the use of nickel super alloy with different welding parameters. Three weld overlaid alloys of inconel625, as wear resistance hardfacing materials on H13 tool steel, with different weld...

Hydroforming process is largely used for the production of tubular parts in various industries, and has advantages such as less weight, higher quality, more strength and fewer production cost compared to the conventional methods of production. The aim of this study is forming a tube-shaped part with a special geometry that has both bulge- and T-zones with tube hydroforming process. The forming ...
