Abstract:
A hydrogen storage device includes a hydrogen storage can, at least one first partition, and at least one second partition. The hydrogen storage can defines a major axis. The at least one first partition is used to partition the space in the hydrogen storage can into at least one compartment. The at least one second partition includes a plurality of sub-compartments. The sub-compartments are arranged linearly in at least one row perpendicular to the major axis.
Abstract:
A method for making Mg(magnesium)-based intermetallic compound uses a thermal process during a melting process to produce largely the Mg-based intermetallic compound. The vapor pressure of Mg is high, thereby Mg is prone to be vaporized from a melt and a wrought solid alloy in the melting process of high temperature, for purifying the wrought Mg-based intermetallic compound. The method may simplify the process and devices for making the Mg-based intermetallic compound, and produce efficiently a larger of high purity Mg-based intermetallic compound.

A lithium (Li)-based alloy and a preparation method thereof are disclosed, in which the lithium metal is wrapped by a metal foil with a higher melting point, followed by subjecting to multi-stage thermal treatment to cast alloy, thereby obtaining the Li-based alloy with high purity-Li.
Abstract:
An aluminum-scandium (Al—Sc) alloy film applied to vehicle lamps and a manufacturing method thereof are revealed. The Al—Sc alloy film contains a trace of scandium so that both temperature for grain refinement and temperature for recrystallization of the film are increased. This results in a fine and smooth surface of the Al—Sc alloy film and the Al—Sc alloy film has better optical reflectivity. Moreover, the Al—Sc alloy film has high recrystallization temperature and high adhesion strength. After high temperature annealing treatment, the Al—Sc alloy film still has higher corrosion resistance.
Abstract:
The present invention provides a method for mass producing any metal alloy. After melting a metal mixture, a mixture of heating, soaking and/or cooling is processed to obtain the alloy even with a trace element added. The metal alloy made by the present invention thus has a high purity and a low cost.
Abstract:
A manufacturing method for an isothermal evaporation casting process is disclosed and to design the manufacturing method for the simple atmospheric casting. The present invention can melt the Mg—Ni alloy with the aspect of totally different melting points thereof, and the other elements can be added during melting simultaneously. Through the Mg—Ni alloy with a suitable weight ratio, the eutectic alloy of Mg/Mg2Ni and high purified γ-phase Mg2Ni can be made. Then adding other elements are to produce the composition of Mg/Ni/M. By way of the manufacturing method of the present invention, the melting equipment is simplified; and, through different manufacturing steps, the purposes of time-saving and low cost are reached; further that, a large amount of the eutectic alloy of Mg/Mg2Ni with different kinds of ratios of Mg, high purified γ-phase Mg2Ni, or the composition of Mg/Ni/M can be obtained.

Abstract:
This invention discloses a method and an apparatus of preventing a gas leak in a pipeline, and the characteristic of expansion occurred when a hydrogen storage material absorbs hydrogen gas is used for setting the hydrogen storage material in a joint between a first pipeline and a second pipeline, such that if hydrogen leaks at the joint, the hydrogen storage material will absorb hydrogen to expand, and the expansion pressure presses the joint to give a tighter connection, so as to achieve the effects of preventing and locking a leak, and compensating a deficiency of tightness due to an accumulated error occurred during the manufacture of the first pipeline and the second pipeline.
Abstract:
A method for producing fine silver-palladium alloy powder includes the steps of: (A) preparing separately a silver nitrate solution and a palladium nitrate solution and mixing the solutions, and then adding a neutralizing and complexing agent to the mixed solutions to adjust the pH thereof to about 2.5-3.5, whereby a first mixture containing silver and palladium ions is obtained; (B) preparing a second mixture containing a reductant and a surfactant; (C) bringing the first mixture into contact with the second mixture at a reaction temperature of 15.degree.-50.degree. C. under stirring in order to permit the silver and palladium ions to be reduced and to coprecipitate so as to form silver-palladium alloy particles; and (D) recovering the coprecipitated silver-palladium alloy particles, thereby obtaining the fine silver-palladium alloy powder.
