摘要： A free casting method according to the present invention includes, a lead-out step for leading out molten metal from a lead-out area provided in a source of supply, e.g. a surface level of the molten metal, to retain the molten metal temporarily by surface films generated on an outer surface, and a forming step for obtaining a formed body by solidifying retained molten metal led out along a set passage depending on a desired casting shape, wherein the retained molten metal is solidified after being formed into the desired casting shape by applying an external force thereto at positions between an unrestrained root portion of the retained molten metal in vicinity of the surface level of the molten metal and a solidification interface defined as a boundary between the retained molten metal and the formed body in the forming step.

摘要： PROBLEMSA method for die-casting that fluidity of molten material is satisfactory and the molten material solidifies with suitable speed is realized.MEANS OF SOLVING THE PROBLEMSA die-casting die 12 comprises a cavity forming surface 9b. A part of the cavity forming surface 9b is coated with a surface treatment layer 24 having a thermal conductivity that increases in connection to an increase in an acted pressure. Satisfactory fluidity is kept at a cavity forming surface 8b coated with the surface treatment layer 24 until a filling of the molten material to the cavity 9 is completed. The molten material is cooled by the cavity forming surface 8b coated with the surface treatment layer 24 increasing the thermal conductivity after the filling of the molten material to the cavity 9 is completed.

摘要： An aluminum alloy according to the present invention includes from 4.0 to 6.0% Mg, from 0.3 to 0.6% Mn, from 0.5 to 0.9% Fe, and the balance of Al and inevitable impurities when the entirety is taken as 100% by mass. By appropriately selecting the composition range of Mg, Mn and Fe, it has been possible to micro-finely crystallize Al (Mn, Fe) compounds while inhibiting the growth of primary-crystal Al. As a result, the resulting aluminum alloy is good in terms of the castability, and shows high strength as well as high ductility.
