On the other hand, as a result of a large amount of Mg alloy members being used as parts in various fields in this way, a large amount of chips from cutting or grinding operations are discharged, and at the same time Mg alloy scraps and A large amount of used waste has also been released.

According to the description of Japanese Patent No. 963, attempts have been made to manufacture a sintered part by utilizing hot pressing, and to perform hot pressing followed by extrusion molding, according to the description of Japanese Patent Laid-Open No. 182806/1990.

さらに結晶粒が微細化されたためと考えられた。On the other hand, when the above method is applied to a Mg alloy chip having a small amount of aluminum (hereinafter referred to as Al) content or no aluminum content, tensile strength and proof stress of a forged product level can be obtained. A considerable effect was recognized such as the elongation being much larger than that of the forged product. The extruded Mg alloy chips show such a greater elongation than the forged product because the chips themselves and the crystal grains are cut into small pieces through the cutting process. It was thought that this was due to miniaturization.

な伸びが得られないものと考えられた。In addition, the above method is applied to M containing a large amount of Al.
When applied to g-alloy chips, tensile strength and proof stress were higher than those obtained by extrusion molding of cast products, and considerable effects were also recognized. However, the elongation did not show the remarkable effect as seen with the Mg alloy chips with a low Al content or no Al content, and remained at the same level as that of a cast product extruded. This is because Mg alloys with a high Al content
Since the amount of 17 Al 12 (intermetallic compound) produced was large, it was considered that sufficient elongation could not be obtained as compared with a Mg alloy containing little Al or not containing Al.

びが十分でないという欠点があった。By the way, many machine parts and the like require considerable elongation in addition to high mechanical strength. For example, a member called an impact bar is installed inside an automobile door to protect an occupant from a side impact. The impact energy that can be absorbed by the impact bar corresponds to the area surrounded by the tensile strength-elongation curve shown in FIG. 6, and it can be said that the higher the strength and the greater the elongation, the greater the energy that can be absorbed and the more effective. As a material for the impact bar, a material that is lightweight and has a high specific strength is preferable, and an Mg alloy containing Al is currently attracting attention. However, as described above, a Mg alloy having a high Al content has a large amount. Since Mg 17 Al 12 is formed, there is a drawback that the elongation is not sufficient.

First, the chips are made by cutting or the like, but the chips in the present invention are not limited to chips obtained by cutting or grinding, and may be chips in the form of chips by a crusher or the like. The obtained cutting chips are formed into a compression-molded body by hot pressing, and are formed into a Mg alloy member by extrusion molding. It should be noted that after extrusion molding, forging molding or the like can be further added. Further, in the present invention, cutting, hot pressing, and extrusion molding may be further repeated once or twice or more.

い。The hot pressing (step of FIG. 1) in the present invention is performed in a temperature range of 200 ° C. to 450 ° C. and a pressure of 7
It is preferably performed at 8 MPa (8.0 Kg / mm 2 ) or more, and under such conditions, it can be performed in the atmosphere.
If the temperature is 200 ° C. or lower, the adhesion of the chips becomes poor, and if the temperature is 450 ° C. or higher, it is necessary to carry out under vacuum from the viewpoint of preventing oxidation. Since chips are chip-shaped, they tend to form a layer in the mold and are easily solidified by unidirectional pressing in the mold, but when other particles such as powder are used in the above process, Pressurization under water pressure is required. In addition, before hot pressing, preliminary compression molding may be performed cold.

The temperature range is the same as that of the hot press, and the extrusion ratio is selected to be 4 or more. This is because if the amount is less than this, the adhesion of the chips becomes insufficient and the chips cannot be used as a member.
