Aluminum and magnesium alloys are of materials for decreasing vehicle weight and consequently reducing fuel consumption. However, forming limitations regarding their low formability at room temperature are found when being manufactured by conventional forming processes. For this reason, development of new forming techniques, such as warm tube hydroforming, is needed to overcome such limitations...

Cold formability of material is influenced by all factors participating in the forming process. The crucial factors include the sheet material, whose formability is the most often evaluated according to its yield point, tensile strength and their ratio, elongation, uniform deformation, their combination, etc. [1]. In the forming process, these material characteristics are significantly influenc...

Various solution-treatments were applied on a rapidly solidified and subsequently rolled Mg-7.50Al-1.07Ca-0.17Mn (mass%) alloy sheet, room-temperature stretch formability, tensile properties, microstructures, textures of the solution-treated sheets have been investigated. Although solution-treatment at 400 °C gives high strengths, sheet shows poor formability with Index Erichsen value 4.8 mm du...

Abstract Third generation of Advanced High Strength Steels (3rd GEN AHSS) for cold stamping combine superior formability and ductility at higher strengths. Their combination with the Laser Welded Blanks (LWB) technology is one answer to improve safety weight reduction vehicules automakers. In this study, a Nakazima test used evaluate forming behavior LWB based 3rd AHSS estimate their Forming Li...
