Abstract:	摘要： A sheet metal trough of aluminum alloys is manufactured by gas-forming process at 500 °C. The product with slope walls is of ~1.2 m long and ~260 mm opening width, comprising two conical sinks at two ends. The depth of one sink apex is ~350 mm, which results in the depth/width ratio reaching 1.4. To form such a complex shape with high aspect ratio, a pre-form of V-shape groove is prepared prior to the gas-forming work. When this double concave trough is turned upside down, the convex contour resembles the back of a twin hump camel. The formability of this configuration depends on the gas pressurization rate profile, the working temperature, material’s micro-structure, as well as pre-form design. The latter point is demonstrated by comparing two aluminum alloys, AA5182 and SP5083, with nearly same compositions but very different grain sizes. 其他題名： J. of Materi Eng and Perform 出版者： Boston: Springer US 出版日期： 2012-11 出處： Journal of materials engineering and performance, 2012-11, Vol.21 (11), p.2290-2294 資源來源： EBSCOhost OmniFile Full Text Select 版權： ASM International 2012 識別號： ISSN: 1059-9495 識別號： EISSN: 1544-1024 識別號： DOI: 10.1007/s11665-012-0179-2 識別號： CODEN: JMEPEG
