摘要： A magnesium alloy structural member includes a base material composed of a magnesium alloy having an aluminum content of 4.5% by mass to 11% by mass, in which the base material has a pair of first and second surfaces, the first surface and the second surface being opposite each other, in which when a distance between the first surface and the second surface is defined as a thickness and when surface area regions are defined as regions extending from the first and second surfaces to positions 20 μm from the respective first and second surfaces in the thickness direction, in at least both the surface area regions, 10 or more fine precipitates are present in any 20 μm×20 μm subregion of each of the surface area regions, each of the fine precipitates containing both Mg and Al and having a greatest dimension of 0.5 μm to 3 μm. Because at least each of the surface area regions is composed of a microscopic texture in which fine precipitates are dispersed, the magnesium alloy structural member has excellent corrosion resistance without anticorrosion treatment and can be used for housings and so forth.

摘要： It is an object of the invention to provide a magnesium welding wire excellent in surface cleanliness and a method for manufacturing the same.A welding wire according to the invention can be manufactured by drawing a base material such as an extruded material made of pure magnesium or a magnesium-based alloy and, after then, by shaving the surface of the thus drawn wire. Execution of the shaving operation makes it possible not only to effectively remove a lubricant and a coating used in the drawing operation but also to effectively remove an oxide generated during the drawing operation. Thanks to this, the thus obtained welding wire is excellent in surface cleanliness. As a lubricant to be used in the drawing operation, preferably, there may be used an oil lubricant or a wet-type lubricant which can be removed easily by a cleaning operation or by a grease removing treatment.

摘要： A steel wire of pearlite structure containing 0.8-1.0 mass % of C and 0.8-1.5 mass % of Si is disclosed. In the cross section of the steel wire the difference in average hardness between a region up to 100 μm from the surface thereof and a deeper region is within 50 in micro-Vickers hardness. The steel wire is manufactured by working a wire rod having the abovementioned chemical composition through shaving, patenting and drawing processes, then strain-relief annealing the resultant wire, and thereafter subjecting the thus annealed to a shot peening process. The steel wire has a high heat resistance and a high fatigue strength, and can be produced through a drawing process without applying a quenching and tempering process.

摘要： A method for heat-treating steel, which method uses a coolant having a large coefficient of heat transfer and which method treats the steel at low cost and in an environment-friendly manner (no pollution), and an apparatus for the method. The heat-treatment method cools austenitized steel in a coolant, which is a mixture of solid particles and water. It is desirable to cool the steel by passing it through a deposited layer of the solid particles in the water. It is desirable that the solid particles be oxides or graphite powders. It is also desirable to fluidize the solid particles. One type of the heat-treatment apparatus submerges steel in a coolant bath described below. The coolant bath comprises (a) a liquid bath that contains water and (b) a solid-particle bath that is partitioned in the liquid bath by a mesh and that contains solid particles. The mesh has openings smaller than the particle diameter of the solid particles. Another type of the heat-treatment apparatus treats steel by using a loaded coolant comprising water and solid particles and a means for forcibly supplying water between the solid particles. It is desirable that this type be provided with a means for fluidizing the solid particles.
