Trans. Nonferrous Met. Soc. China 26(2016) 1546-1554 Hot bend assisted gas forming of AA5083 sheet for making V-shaped trough containing deep uneven concavities Jung-Sung TANG, Shyong LEE Department... superplastic AA5083. The auxiliary yet influential procedure of mechanically hot bending the flat sheet into a V-shape precedes the gas-forming process. In this first quick hot-bending operation, buckling......

experiments and recording responses A non-consumable tungsten electrode shielded by inert gas, is used to strike an electric arc with the base metal. The heat generated by the electric arc is used to melt and join the base metal. The shielding gas is argon and a valve meter controls the flow rate of the shielding gas. A single pass welding is performed because the thickness of the titanium alloy......
Abstract: Several rheocasting processes are developed or applied worldwide in the metal forming industry. One of the new rheocasting processes is the gas induced semi-solid (GISS) process. The GISS process... of this process was reported. Key words: gas induced semi-solid; rheocasting; die casting; formation mechanism; industrial applications 1 Introduction Semi-solid metal forming employing the rheocasting......
developed by treating with CO2 or industrial waste gas at room temperature, while no separate binders were used. When the pellet was added into hot metal bath (carbon-containing molten iron.... Furthermore, the pellet enhances waste utilization and use of CO2 in waste gas. In this article, emphasis is given on studying the behavior of these pellets in hot metal bath during melting and refining along......

strength of nickel based super-alloy at room temperature, the main forming method for thin-walled curved surface parts is hot-forming. The sheet metal plastic deformation ability makes the thin-walled... be considered after assembly welding for thin-walled parts. Moreover, hot-forming would influence the microstructure and surface quality of parts[4-7]. One of the ways to solve these problems is to develop a new......
The properties of ceramic die material required for use in superplastic forming mainly include good hot strength to resist cracking and fracture, low hot deformation and minimal chemical interaction... in the air inlet hole was screwed to the gas-pressure meter of the nitrogen cylinder. The Ti6Al4V sheet was heated at 15 ℃/min up to 930 ℃ and held for 30 min before blow forming. Then, the nitrogen......
