Název v původním jazyce

Effect of Manganese and Chromium on the Microstructure, Texture and Properties of Twin-Roll Cast Al-Mg Sheets

Popis výsledku v původním jazyce

The need for low-cost aluminium sheets for automotive applications is nowadays recognised. Car-body inner panels are manufactured from Al-Mg alloys. Al-Mg twin-roll cast (TRC) sheets are a suitable substitution for direct-chill (DC) cast sheets. TRC sheet manufacturing is cost effective but needs a detailed knowledge about the effect of composition on alloy processing response and the final properties of semi-products for the demanding automotive sector. The results of evaluation of the effect of minoralloying elements (Mn and Cr) on the microstructure, texture and properties of 1.0 mm Al-Mg TRC sheets are reported. Manganese and chromium effectively hinder recrystallization during homogenisation and this effect projects up to final sheet microstructure and properties. Alloys with Mn and Cr have higher strength without any formability penalty. Mn and Cr additions result in better balance between cube and retained rolling texture, which is a pre-requisite for good formability.
