Definitions

  • This invention relates to production of as-cast aluminum alloys with ultra-fine grain structure. More particularly, it relates to methods of adding a grain refiner to a molten aluminum alloy at levels which reduce the grain size to less than about 200 microns.
  • the size and shape of grains in as-cast aluminum alloy impacts properties of wrought or cast products. Casting with large grains, particularly dendritic grains, is highly prone to cracking during casting and reduce ductility, fracture toughness and fatigue properties. Reduction of the size as well as the form of the grains may be accomplished by mechanical or electromagnetic stirring to break up the grains. Grain size may also be controlled metallurgically by adding a grain refiner to the aluminum alloy melt.
  • a typical grain refiner used for aluminum alloys is cither an Al-Ti-B alloy or an Al-Ti-C alloy in the form of a rod or waffle.
  • a gain refiner consists of numerous fine boride or carbide particles in an aluminum matrix.
  • grain refiners When these grain refiners are added to the aluminum alloy melt, the boride or carbide particles are dispersed into the melt and serve as nucleating sites for grains during solidification.
  • Commercially available grain refiners include alloys containing about 3-5 wt, % Ti and about 0.15-1 wt. % B or C and the balance Al. According to this practice, a residual amount of Ti is present in or is added to the aluminum melt (e.g. less than 0.015wt. %), and a controlled amount of the grain refiner is added thereto which increases the total Ti concentration in the final melt by about 0.001-0.003 wt. %. In this manner, the amount of B or C added to the melt via the grain refiner is about 0.0001-0.001 wt. %.
  • the addition of grain refiners at these conventional levels can control the size of dendritic grains to be about 250-1000 microns, For certain cast or wrought aluminum prodllots, such a grain structure is sufficiently fine and cracking
  • ultra-fine grain size may be achieved by supersaturating a molten alloy with dispersoid-forming elements such as Zr, Mn, Cr, V, Ti, Sc and Hf as disclosed in U.S. Patent No. 6,004,506. That process requires the addition of a specialized, pre-alloyed ribbon of material containing the dispersoid-forming elements into a pool of molten metal formed during ingot casting. Accordingly, a need remains for a method of producing aluminum alloys with ultra-fine grain structure using readily available additives.
  • the inventive method includes the steps of a) providing a molten aluminum alloy including an alloying element selected from the group consisting of Ti, Sc, Zr, V, Hf, Nb and Y; b) adding a grain refiner to the molten aluminum alloy to form a melt, wherein the grain refiner comprises (i) Ti and (ii) B or C, such that the concentration in the melt of B or C after addition of grain refiner is about 0.003-0.010 wt. %; and c) solidifying the melt to form an ingot.
  • the alloying clement is Ti at a concentration of about 0.015-0.030 wt.
  • the alloy may be a wrought alloy of the 1XXX, 2XXX, 3XXX, 5XXX, 6XXX, 7XXX or 8XXX Aluminum Association (AA) series, preferably an alloy of the 2XXX or 7XXX AA series or a casting alloy such as a 2XX, 3XX, 1XX, 5XX, 7XX or 8XX series alloy.
  • Particularly preferred wrought alloys are 7055 and 7050 alloys.
  • the grains in the ingot formed according to the present invention are sited about 200 microns or less, preferably 100 microns or less.
  • the present invention includes a method of controlling the grain size in cast aluminum alloys to about 200 microns or less.
  • an alloying clement is added to a molten aluminum alloy.
  • Preferred residual alloying elements are Ti, Sc, Zr, V, Hf, Nb and Y, more preferably Ti and Sc.
  • a preferred concentration of the alloying element Ti in the molten aluminum alloy is about 0.015-0.030 wt. %.
  • the alloying element is Sc
  • a preferred concentration of residual Sc in the molten aluminum alloy is about 0.030-0.1 wt, %.
  • the alloying element is Zr, V, Hf, Nb or Y
  • the preferred concentration thereof is on the order of the preferred concentrations of Ti and Sc.
  • a grain refiner is added to tho molten aluminum alloy containing the residual alloying element to form a melt.
  • Commercially available grain refiners are alloys consisting of Ti and B or C with the balance aluminum. Typical concentrations in the grain refiner are about 3-5 wt. % Ti and about 0.15-1 wt. % B or C. The final concentration of B or C in the melt from the grain refiner is about 0.003-0.010 wt. %.
  • Suitable commercially available grain refiners have compositions such as 3 wt. % Ti, 1 wt. % B and balance Al (referred to as Al-3%Ti-1%B).
  • Al-3%Ti-1%B Al-5%Ti-1%B, Al-3%Ti-0.2%B, Al-5%Ti-0.2%B, Al-3%Ti-0.15%C, or Al-3%Ti-0.3%C.
  • These grain refiners typically are provided in the form of a rod or waffle, The ratio of B or C to Ti in the grain refiner is normally fixed; hence, the amount of grain refiner added to the melt controls the final amount of Ti present in the melt. For example, in order to achieve a concentration of B of about 0.003-0.010 wt.
  • the present invention may be used to control grain size in wrought and cast alloys.
  • Suitable alloys include Aluminum Association (AA) wrought alloys of the 1XXX, 2XXX, 3XXX, 5XXX, 6XXX, 7XXX and 8XXX series and cast alloys of the AA 2XX, 3 XX, 4XX, 5XX, 7XX and 8XX series. Alloys of the AA 2XXX and 7XXX series are particularly suited to treatment according to the present invention.
  • As-cast aluminum alloy produced according to the present invention has globular grains which are about 200 microns or less in size, typically about 80 microns in size.
  • conventional grain refining practice of adding a grain refiner of Al-3%Ti-1%B such that the concentration of B in the melt is 0.001 wt. % produces dendritic grains sized about 1000 microns. These large dendritic grains interlock with each other and render the cast alloy rigid and prone to cracking, whereas the small, globular grains formed by the method of the present invention reduce crack initiation during casting and improve formability during deformation.
