| Abstract Scope |
Magnesium (Mg) alloys are one of the best suited materials to fulfil demands of the global large sector industries seeking lightweight sheets having high specific strength and good ductility. However, development of defect free magnesium (Mg) alloys sheets with excellent strength-ductility synergy is extremely challenging due to their hexagonal closed packed (hcp) crystal structure and poor ductility/formability at room temperature. Therefore, the present research is focused on establishing a single step manufacturing process by pioneering the combined effect of rolling parameters namely temperature, load and speed on quality, mechanical properties and manufacturability of Mg sheets. The scientific knowhow and various associated mechanisms were comprehensively studied using Finite Element Analysis (FEA) and extensive experimentations. A processing window revealing high strength/ductility and strength-ductility trade-off/synergy zones are established to produce application specific Mg sheets. This research opens a new pathway for producing high performance Mg sheets exhibiting a promising potential for industrial use. |
