摘要： A process is described for forming a composite cast article comprising an aluminum-silicon alloy matrix containing strontium as a modifier and a preform of bonded-together Al₂O₃ fibres incorporated in the matrix, in which the preform is infiltrated under pressure by a melt of the alloy and the composite article thus formed is allowed to solidify by cooling. According to the novel feature, by utilizing a specific amount of strontium as modifier in the range of about 0.5 to 1.0% by weight, it is possible to obtain a satisfactory modification of the alloy within the composite.

摘要： Aluminium-lithium alloys are cast on a twin-roll caster under an inert atmosphere to give a cast slab from 2-7 mm, and preferably 2-4 mm, thick. Alloys may be of the 2000 or 8000 Series. Casting speed may be from 50-200 cm/min and the diameter of the rolls from 20-50 cm. The alloys are more easily cast with less centre-line segregation than are Al-Mg alloys of comparable long melting range. The case slabs are in a suitable form for cold rolling to make sheet.

摘要： A method of producing a composite cast article having a metal matrix containing divided dispersible solid material, i.e. divided solid filler, such as reinforcing fibers or particles, wherein a melt of the metal matrix is placed in a die cavity, a preheated preform of a divided solid filler is placed on top of the melt and pressure is exerted on the preform in a direction parallel to the cavity axis for forcing the preform downwardly into the molten metal whereby the molten metal fully infiltrates the the preform filler, and the resultant cast article is solidified by controlling heat flow within the die cavity in such manner that a solidification from advances unidirectionally, along the cavity axis, entirely through the metal-infiltrated preform layer, while the metal ahead of this front within and at least immediately beyond the preform layer remains molten.
