Abstract

PURPOSE:To cast an Mg alloy having superior characteristics such as impact force, elastic force, etc., by mixing trace amounts of metallic Na with a molten alloy for Mg-Al-Zn castings. CONSTITUTION:The metallic Na is mixed with the molten metal for alloy castings mainly composed of Mg, Al and Zn by traces of about 0.1-2%. Then casting is carried out by use of the above molten metal by the ordinary method, when crystalline nuclei are formed around metallic Na seeds and these crystalline nuclei are bonded each other so that the metallic structure forms into honeycomb construction. In this way, Mg-type castings having improved mechanical characteristics such as impact force, elastic force, etc., can be obtained.

ことが技術的課題である。The technical problem of the present invention is to provide a magnesium casting method that solves these drawbacks and improves mechanical properties such as impact force and expansion/contraction force by mixing a small amount of metallic sodium into alloy casting hot water. It is.

〔問題点を解決するための手段〕[Means for solving problems]

マグネシウム、アルミニウム、亜鉛を主成分とする合金
鋳物湯の中に微量の金属ナトリウムを混入し、常法通り
鋳造する。A small amount of metallic sodium is mixed into an alloy casting bath whose main components are magnesium, aluminum, and zinc, and cast using a conventional method.

〔実施例〕〔Example〕

マグネシウム　　　　　９０％ アルミニウム　　　　６〜９％ 亜　　　　　　鉛　　　　　１〜３％ 金属ナトリウム　　　　ｏ、ｉ〜２％ 溶湯温度　６５０〜７００℃ 〔発明の効果〕 本発明は、上述の様に構成したから金属ナトリウム′の
胞子を種にしてその周囲に金属組織の結晶格が出来る。Magnesium 90% Aluminum 6-9% Zinc 1-3% Sodium metal o, i-2% Molten metal temperature 650-700°C [Effects of the Invention] Since the present invention is constructed as described above, the spores of sodium metal' It becomes a seed and a crystalline structure of metal structure is formed around it.

従って、金属組織をみると、沢山散在されてい構造にな
