摘要： Aluminum substrates are electrograined for lithographic printing in an electrolytic cell using an electrolyte of hydrochloric acid or nitric acid, and a "regulated alternating current" whereby the inter-electrode voltage is applied with a higher anodic voltage than the cathodic voltage, the ratio of cathodic coulombic input to anodic coulombic input is less than one and preferably in the range of 0.3-0.8, and the anodic half cycle period or time is not longer than the cathodic half cycle period or time, thereby to impart to the substrate a "pits-within-a-pit" grain structure uniformly over its entire surface.

摘要： A small grain promoting aluminum-titanium boron mother alloy containing 3.5 to 7.5 wt% of titanium and 0.1 to 0.3 wt% of boron in a ratio by weight of boron/titanium of 1:20-40. The alloy is preferably prepared by admixing finely divided titanium alkali fluoride and alkali borofluoride to molten aluminum at temperatures not exceeding 900 DEG C, the aluminum reducing the titanium and boron in such fluorides to free metal. The mother alloy can be dispersed into the mass of molten aluminum to be improved which is then ready to be cast into a desired shape.

摘要： A die assembly for squeeze casting of metals wherein a tubular reinforcing die is set on a base, a forming die consists of split dies is inserted in internal contact with the reinforcing die and the surface in internal contact with the reinforcing die is tapered so as to be narrower downward so that, in case a downward force is applied by a sealing die to a molten metal poured into the forming die, the split dies may be pushed in downward along the tapered surface to prevent the molten metal from spitting out.
