PRESSING MATERIAL OF MAGNESIUM ALLOY, METHOD FOR PRODUCTION THEREOF, REINFORCER, INTERIOR MATERIAL, BODY STRUCTURE OF RAILWAY VEHICLE AND BODY STRUCTURE OF TRAFFIC TRANSPORTATION MEANS

摘要

PROBLEM TO BE SOLVED: To provide a pressing material of magnesium alloy having sufficient strength, capable of reducing weight and capable of improving rigidity as a structure, a method for production thereof, and to provide a reinforcer, interior material, body structure of railway vehicle and body structure of traffic transportation means.;SOLUTION: A pressing material 7A is a magnesium alloy including calcium and is prepared by bend-processing the magnesium alloy using a press die. The pressing material 7A is a shape for configuring a body structure 2 by combining with an outside plate 3, and functions as a main frame configuring the body structure 2. The pressing material 7A is arranged inside an outside plate 3 (in-vehicle side) in such a form as being orthogonal to the outside plate 3. The thickness of the material 7A is preferably 1 mm or more but 6 mm or less. Besides in the material 7A, the ratio R₁/R₂ of an internal diameter R₁ of a bending part 7d to an external diameter R₂ thereof is preferably 0 or more but less than 6, and also preferably, the ratio R₂/t of the external diameter R₂ to a plate thickness t is 0.2 or more but 12.0 or less.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2019,JPO&INPIT
