  One of the basic needs in the defense industry is the manufacturing of thin-slice and high-plasticity pieces, but thin-slice pieces with complex geometric shapes can often not be manufactured by conventional ways or cost more than conventional ones. Usually, the method of manufacturing these pieces is to use the spinning. In addition to quality and precision in size, these pieces must be of high strength, which makes them difficult to manufacture. In this study, spinning with thermal methods in High Temperature Furnace was used to form a bowl. The Hastelloy x alloy was used for fabrication. All tensile, hardness and microstructure tests were performed on the formed part by optical microscopy after forming and heating processes. After completing the process of manufacturing, the quality of its dimensions were also measured by a 3D optical scanner. The Hastelloy x alloy loses its plasti.. Read More»
