Warm deep-drawing and post drawing analysis of two Al–Mg–Si alloys

Journal of Materials Processing Technology, 2014
The increasing use of aluminium alloys in light weight structural applications is restricted mainly due to their lower room temperature formability compared to steels. Forming at higher temperature is seen as a promising solution to this problem. In the present investigation two Al-Mg-Si alloys (EN AW-6016 and EN AW-6061) were deep-drawn at room ...

Deep-drawing of magnesium alloy sheets at warm temperatures

Journal of Materials Processing Technology, 2007
Abstract In magnesium alloy sheet products have been attracting more and more attention in recent years because of their application potentials as coverings of portable electrical devices and automotive panels. However, magnesium alloy sheets are usually formed at temperatures between 250 and 400 °C because of their poor plasticity at room ...

Warm deep drawing of magnesium alloy sheets — formability and process conditions

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2008
The influence of deformation conditions on the formability of magnesium alloy was systematically investigated using the experimental method and finite element analysis. The research activity aimed to gain further insight into the formability of magnesium alloy AZ31 (aluminium 3 wt per cent, zinc 1 wt per cent) and to have first-hand knowledge of the ...

Numerical simulation on warm deep drawing of magnesium alloy AZ31 sheets

Materials Science and Engineering: A, 2009
Warm forming of magnesium alloys has attracted much attention due to the very poor formability of Mg alloys at room temperature. In the present paper, the warm deep drawing of magnesium alloy AZ31 (3 wt.% Al, 1 wt.% Zn) sheets was studied by both the experimental approach and the finite element analysis.

Metallurgical Studies of Austenitic Stainless Steel 304 under Warm Deep Drawing

Journal of Iron and Steel Research International, 2014
Austenitic stainless steel 304 was deep drawn with different blank diameters under warm conditions using 20 t hydraulic press. A number of deep drawing experiments both at room temperature and at 150 °C were conducted to study the metallography. Also, tensile test experiments were conducted on a universal testing machine up to 700 °C and the broken ...
