A deformable Al-Mn alloy contains Si (0-0.6%), Fe (0-0.7%), Cu (0-0.3%), Mn (0.3-1.6%), Mg (0-1.3%), Ti (0.005-0.15%), RE (0-0.4%), B (0-0.03%), impurities (0-0.7%) and Al (rest). Its preparing process includes such steps as smelting fine-crystal Al ingot, adding others, smelting Al-Mn alloy, and pressure machining.

The invention relates to high-strength Mg-Y-Ni-Mn alloy and a manufacturing method thereof. The high-strength Mg-Y-Ni-Mn alloy comprises 5.0-12.5% of Y, 2.0-6.0% of Ni, 0.4-1.0% of Mn and the balance magnesium and inevitable impurities. The alloy is manufactured through the following process of material preparing, vacuum melting ingot casting, cyclic homogenizing annealing, extruding and double aging. Materials do not need to be refined; the extrusion ratio is low (lambda=11); the limitations that the manufacturing process of high-performance magnesium alloy is complex and the manufacturing conditions are rigorous are broken; the process is simple; transportability is high; operation is easy, the room temperature tensile strength and the yield strength of the alloy are obviously improved; the high-performance magnesium alloy can be directly produced under existing industrial conditions; the problem that the application of the Mg alloy is limited due to the poor mechanical performance of the Mg alloy is solved; and the application range of the magnesium alloy is expanded.

An objective of the present invention is to provide an energy conversion and storage equipment which is capable of efficiently generating hydrogen using varying electric power generated from renewable energy and is capable of storing the hydrogen. The invention is an apparatus for converting and storing renewable energy in which hydrogen is produced with a water electrolysis device using the varying electric power generated in renewable-energy equipment and the hydrogen is stored, the apparatus being characterized in that the water electrolysis device includes an oxygen generation electrode which comprises an Ir—Mn alloy oxide. Due to the application of the electrode, with which water can be electrolyzed using the varying electric power generated from renewable energy, the system suffers little electrode deterioration even when the varying electric power is used, and it is possible to highly efficiently produce and store hydrogen for a long period.
