A device for fixing biological soft tissue is endowed with strength and deformation performance for being used as a device for coupling biological soft tissue that has been cut or separated due to an incision or the like during a surgical procedure, and is completely degraded in vivo and discharged after adhesion of the soft tissue or after healing of the incision tissue. The device is composed of a ternary Mg alloy material of Mg—Ca—Zn. In the Mg alloy material, the Ca and Zn are contained within the solid-solubility limit with respect to the Mg. The remainder is composed of Mg and unavoidable impurities. The Zn content is 0.5 at % or less. The Ca and Zn content has a relationship of Ca:Zn=1:x (where x is 1 to 3) by atom ratio.

The invention relates to a method of casting a metal alloy ingot. The method includes providing an on one side open-ended mould having a mould cavity, positioning the open-ended mould such that the mould opening points side-wards or down-wards, providing a casting container with an upwardly positioned aperture, and filling said casting container with molten metal for one casting operation. The method also includes locating the casting container below the mould while the mould opening points side-wards or down-wards, and rotating the mould together with the casting container to a position whereby the mould opening points upwards such that the molten metal is conveyed into the open-ended mould until a desired thickness. Molten metal in the open-ended mould is cooled directionally through its thickness where the solidification front remains substantially monoaxial.
