For studies and investigates about the ocean, various underwater vehicles are used. All these vehicles controlled by electronics. Electronic devices need solid pressure vessel to protect them from seawater and water pressure. For electronic devices using under water, defer from using in the air, they need solid pressure vessel. Particularly, water pressure is increasing according to depth, so the pressure vessels need to make strong. But strong vessels are very heavy weight. It is not good at treatment. Especially for long cruising vehicle that is worse about energy effect. If we can make pressure vessels and frames with lightweight and strong material, we can reduce weight of vehicles. And that help weight loss of buoyancy materials and the expansion of the payload. We start to development of new pressure vessel with magnesium alloy that specific gravity is light than titanium alloy and the aluminum alloy. Our development aim is stronger than Titanium (Ti-6Al-4V) at ratio of (tensile strength) by density. The Ti-6Al-4V is usually used light and strong material for pressure vessel. Our development target is 1.3 times stronger than Titanium alloy (Ti- 6Al-4V) at ratio of (tensile strength) by density as strength of a pressure vessel. The paper presents experiment results of the evaluations examination obtained by using specimens and a small pressure vessel made by Magnesium alloy. |
