Title:
COIL MATERIAL AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2011/122390
Kind Code:
A1
Abstract:
Disclosed is a method for producing a coil material that forms a coil material by winding a plate-like material consisting of a metal into a cylindrical shape. The plate-like material is a cast material of magnesium alloy discharged from a continuous casting machine and has a thickness t (mm) of 7 mm or less. Also disclosed is a coil material that can contribute to improvements in producibility of high-strength magnesium alloy plate materials by being wound by a winding machine and having temperature T (°C) directly before winding a plate-like material (1) controlled to a temperature such that the surface distortion ((t/R) x 100) given by the thickness t and bending radius R (mm) for the plate-like material (1) is less than the elongation of the plate-like material (1) at room temperature.
