    摘要： In a semi-solid alloy including a large amount of a liquid phase portion, that is, semi-solid alloy with less than 50% of solid phase rate, there is a tendency for a solid phase portion to concentrate into the central portion in the direction of thickness, that is the internal portion. In order to enhance corrosion resistance at a portion where high corrosion resistance is particularly required in parts molded by semi-solid injection, the above tendency is utilized. By utilizing the tendency, a layer consisting of a liquid phase portion is partially formed at the semi-solid state on a surface portion where high corrosion resistance is required.

    摘要： The manufacturing method of plastically formed products prevents the generation of cracks at the time of plastic working, thereby increasing the productivity. It is also prevented that the metallic particles constituting the product become large and rough in structure. In the manufacturing method, only the compact treatment and the vacuum deaeration treatment are carried out prior to the extrusion treatment, without the pressure-heat treatment performed. Therefore, processing steps prior to the extrusion treatment are simplified, so that the productivity of the plastically formed products is improved and the metallic particles are prevented from being large and rough. The diffusion treatment between the extrusion treatment and the forging treatment enhances the adhesion at the inner part of the extruded material in the radial direction, whereby the generation of cracks at the time of plastic working is avoided.

    摘要翻译： 塑性成型制品的制造方法防止在塑性加工时产生裂缝，从而提高生产率。 也可以防止构成产品的金属粒子变大，结构粗糙。 在制造方法中，在进行挤压处理之前，仅进行紧密处理和真空脱气处理，不进行压力热处理。 因此，在挤出处理之前的处理步骤简化，从而提高了塑性成形产品的生产率，防止金属颗粒变大和粗糙。 挤出处理和锻造处理之间的扩散处理增强了挤出材料的径向内部的粘附性，从而避免了在塑性加工时产生裂纹。

    摘要： This invention is to provide a magnesium alloy cast material capable of manufacturing a wheel, a large-sized forged piece such as wheel having properties equivalent to those of aluminum molten forged member, directly from the state of continuous cast material. The magnesium alloy cast material is a nearly intermediate alloy composition between conventional AZ61 alloy and AZ80 alloy, comprising Al: 6.2 to 7.6 wt. %, Mn: 0.15 to 0.4 wt. %, Zn: 0.4 to 0.8 wt. % and Mg: balance, and casting by defining the mean crystal grain size under 200 .mu.m. The forgeability is excellent, and when forged, a forged piece superior in mechanical properties and corrosion resistance to the aluminum molten forged member can be manufactured.

    摘要： An article of manufacture made of a magnesium alloy is made by casting the magnesium alloy to provide a billet, forging the billet to render material of the billet to have an average crystalline particle size of not greater than 100 .mu.m; and carrying out a T6 treatment (a solution treatment and an artificial aging treatment) with respect to the billet. Physical properties such as, for example, the tensile strength, elongation and the like of the article are considerably improved by virtue of the synergistic effect of the micronized crystalline particles and the T6 treatment.
