The present invention relates to an amorphous alloy and a method for manufacturing thereof. The amorphous alloy according to the present invention includes has a chemical formula of Feioo-a-b-c-d-e-f-gCraMobCcBaYeMflg. Here, the M is at least one selected from a group consisting of Al, Co, N1 and Ni, and the I is at least one selected from a group consisting of Mn, P, S, and O as impurities. The a, b, c, d, e, f, and g are satisfied with the compositions of 16.0 wt %&#x2266;a&#x3c;22.0 wt %, 15.0 wt %&#x3c;b&#x2266;27.0 wt %, 2.0 wt %&#x2266;c&#x3c;3.5 wt %, 1.0 wt %&#x3c;d&#x2266;1.5 wt %, 1.0 wt %&#x3c;e&#x2266;3.5 wt %, 0.25 wt %&#x3c;f&#x2266;3.0 wt %, and 0.01 wt %&#x2266;g&#x3c;0.5 wt %, respectively.

Amorphous alloy and manufacturing method thereof

A nanometer-sized porous metallic glass and a method for manufacturing the same are provided. The porous metallic glass includes Ti (titanium) at 50.0 at % to 70.0 at %, Y (yttrium) at 0.5 at % to 10.0 at %, Al (aluminum) at 10.0 at % to 30.0 at %, Co (cobalt) at 10.0 at % to 30.0 at %, and impurities. Ti +Y+Al+Co+the impurities=100.0 at %.

Ti+Y+Al+Co+the impurities=100.0 at %.

An apparatus for vertical squeeze casting, which alters conventional apparatuses for vertical squeeze casting using squeeze casting methods to manufacture highly-detailed cast products of high quality by locally pressing the molten metal injection filled into the metal mold cavity, by improving the molten metal supplying mechanism and cast product extraction method, so that local pressing of the cast product from all vertical and lateral directions is enabled, thereby enabling the production of cast products with many variations in thickness and complex structures.
