The paper presents the results of a study of drawability of thin AZ31 magnesium alloy metal sheets. These studies are a continuation of experiences in presenting the characteristics of technological plasticity of strips made of magnesium alloy which have been cast between rolls in vertical and horizontal systems called ‘twin-roll casting’. In the context of previous experiments conducted at the Institute of Material Technology of the Silesian University of Technology in cooperation with the Technical University - Bergakademie Freiberg (Germany), drawability of these strips at elevated temperatures has been comprehensively defined while using forming limit curves. Due to low formability of magnesium alloys at ambient temperature, formability tests - including cup forming tests presented in this paper - have been carried out in heated dies at temperature range of 200°C to 350°C. A modern AutoGrid digital local strain analyzer has been used in the examinations and the method of image analysis of deformed coordination nets has been applied. Quantitative and qualitative impact of deformation temperature upon the drawability effects of AZ31 magnesium alloys products have been evaluated.

Keywords: drawability at elevated temperature; local strain distribution measurements; forming limit curve; AutoGrid strain analyzer; thin sheet metals; magnesium alloys; AZ31; cup forming test
