Open the CIPO recordAbstract From the Canadian patent
A method of producing magnesium alloy strip suitable for use in the , production of magnesium alloy sheet by rolling reduction and heat treatment involves casting magnesium alloy as strip using a twin roll casting , installation. In the casting the thickness and temperature of the strip exiting from between rolls of the installation are controlled whereby the strip has a microstructure characterised by a primary phase having a form selected from deformed dendritic, equiaxed dendritic and a mixture of deformed and equiaxed dendritic forms. The resultant strip is amenable to production of sheet material by application of a homogenizing heat treatment followed by rolling and annealing.
