Warm Deep Drawing Of Rectangular Cups With Magnesium Alloy AZ31 Sheets
AIP Conference Proceedings, 2007Recently, magnesium alloys have been widely applied in automotive and electronic industries as the lightest weight structural and functional materials. Warm forming of magnesium alloys has attracted much attention due to the very poor formability of Mg alloys at room temperature.

Process Parameter Effects on the LDR in Warm Deep Drawing of Magnesium Alloys
Key Engineering Materials, 2009The present work is focused on the investigation of the role of temperature and punch speed in warm deep drawing of AZ31 magnesium alloy. To this purpose, an experimental campaign, defined using a proper DOE approach, has been performed. The experimental results, in terms of the Limiting Drawing Ratio, have shown that drawability is strongly affected ...

Numerical Analysis of Warm Deep Drawing for Ti–6Al–4V Alloy
2015The objective of this study was to focus on the current state of finite element methods with respect to reliability in modeling of sheet metal forming processes. The trustworthiness of the FE simulations largely depends on the input material models used and correctness of the input material data.

Finite Element Analysis Of The Warm Deep Drawing Process Of Magnesium Alloys
AIP Conference Proceedings, 2004The use of magnesium alloys meets the need of reducing weight of components (especially in automotive and aerospace industry) keeping unmodified their mechanical properties. The adoption of magnesium alloys in sheet forming processes (which allows optimal mechanical properties) is still limited, due to their low formability at room temperature caused ...

Investigation on Formability of AISI 304 Circular Cups by Warm Deep Drawing
Advanced Materials Research, 2011Deep drawing is one of the sheet metal forming processes used widely in industries like automobile, aerospace etc. In drawing operation, the limiting draw ratio (LDR) is used as an index of drawability of a material. In this investigation, stainless steel AISI 304 grade blanks of 1.0 mm thickness with different diameters are drawn into a circular cups ...

Comparative study of warm and hydromechanical deep drawing for low-carbon steel
The International Journal of Advanced Manufacturing Technology, 2015Deep drawing is a process of converting sheets into cup-like-shaped components. It is a complex process, and process parameters play an important role. In this paper, two deep drawing processes namely warm deep drawing and hydromechanical deep drawing are compared. A 20-t hydraulic press is used to draw the cups.

Development of an analytical model for warm deep drawing of aluminum alloys
Journal of Materials Processing Technology, 2008In this study, an analytical model was developed to investigate the effects of material, process, and geometric parameters in the warm forming of aluminum alloys under simple cylindrical deep drawing conditions. The model was validated with both existing experimental findings in the literature and FEA results. The effects of the main process parameters

Failure and formability studies in warm deep drawing of Ti–6Al–4V alloy
Materials & Design, 2014Abstract Deep drawing experiments have been performed in order to study formability of Ti–6Al–4V alloy sheet at temperature ranging from room temperature to 400 °C. It is found that below 150 °C, formability of the material is very poor and above 150 °C till 400 °C, limiting drawing ratio (LDR) is found to be 1.8 which is substantially lesser than ...

Simulation Experiment on Friction Coefficients during Warm Deep Drawing of Magnesium Alloy Sheet
Applied Mechanics and Materials, 2010In sheet metal forming, friction condition between sheet metal and mold is a very important problem for it influences the formability and the variation of stress, strain and thickness of sheet metal, and so on. Simulation experiments had been done to measure friction coefficients online at punch and die rounded corners under different process ...
