Application of the Flame-Retardant Magnesium Alloy to High Speed Rail Vehicles

Texture, Microstructure, and Mechanical Properties of Calcium- Containing Flame-Resistant Magnesium Alloy Sheets Produced by Twin-Roll Casting and Sequential Warm Rolling

“…Magnesium (Mg) alloys are attracting attention as metallic materials of the next generation because of their good specific strength, specific rigidity, earthquake resistance, and machinability, as well as the abundance of resources available for their production [1]. Because of their lightness, Mg alloys are expected to be suitable materials for replacing aluminum alloys in automobiles and in rail and aerospace transportation devices [2,3]. Research has been performed on improving the mechanical properties, corrosion resistance, and workability of Mg alloys [4,5].…”

Development of Small-Scale Impact Three-Point Bending Test Apparatus and Evaluation of Impact Fracture Properties of Mg-6%Al-1%Zn-2%Ca Alloy

“…The AZX612 alloy is the ame-resistant Mg alloy by addition of 2 mass% calcium 19,20) . Recent years, these frame-resistant Mg alloys bearing Ca are desired to apply to the components of bullet trains 2,21) . Figure 4(b) shows the optical micrograph of the initial microstructure of the extruded AZX612 alloy.…”

“…Recent years, in order to reduce the environmental load, magnesium alloys, which have less density than that of steels and aluminum alloys, are desired to application for the structural component of vehicles 1,2) . Several studies have reported that addition of rare earth elements, and grain re nement can improve the mechanical properties of Mg alloys [3][4][5][6] .…”

Effect of Antigravity-Suction-Casting Parameters on Microstructure and Mechanical Properties of Mg–10Al–0.2Mn–1Ca Cast Alloy

“…As Mg resources are also abundant, 1) Mg alloys are increasingly being used as casings and vehicle parts in order to improve energy efficiency and to reduce weight. 2) On the other hand, many vehicle components use Al alloys. 2) In order to replace Al alloys with Mg alloys, the rigidity, mechanical properties and noncombustibility of the Mg alloys need to be improved before they can serve as structural parts, and the manufacturing costs must be reduced.…”

“…2) On the other hand, many vehicle components use Al alloys. 2) In order to replace Al alloys with Mg alloys, the rigidity, mechanical properties and noncombustibility of the Mg alloys need to be improved before they can serve as structural parts, and the manufacturing costs must be reduced. Akiyama et al showed that adding more than 0.5 mass% of Ca metal in Mg alloys can increase the ignition point to above 800°C, thereby improving noncombustibility.…”
