Definitions
- the alloy is preferably prepared by admixing finely divided titanium alkali fluoride and alkali borofluoride to molten aluminum at [52] US. Cl.
- the present invention relates to an aluminumtitanium-boron mother alloy which is adapted to be added to a molten mass of aluminum or aluminum alloy for castings to promote the formation of small crystal grains in such castings.
- a mother alloy of aluminum containing titanium and boron as the medium for adding both titanium and boron to molten aluminum and one alloy designed for this purpose is commercially available.
- This commercial alloy has the disadvantage that its grain size reducing effect decreases with the retention time of the molten metal before casting. Therefore, in aluminum casting using a furnace of large capacity, in which a long time is required for the molten metal to be freed of gases and impurities and for all the molten metal to be poured into the molds, there can occur a significant difference in the ultimate grain size from the beginning to the end of the casting operation.
- an aluminum-titanium boron alloy of this kind is effective for reducing the grain size in aluminum castings because the intermetallic compounds TiAl and TiB formed in the mother alloy act when added to aluminum on each other to greatly promote the generation of crystalline nuclei of aluminum.
- a suitable mother alloy can be readily prepared using finely divided tita' nium alkali fluoride and alkali borofluoride as the sources of titanium and boron, these fluoride powders being added to molten aluminum of the mother alloy in proportions such that the ratio of boron to titanium contained in the alloy is about 1:20 -40 by weight, the melting temperature being as low as possible below about 900C.
- the present invention provides a small grain promoting aluminum-titanium-boron mother alloy which is prepared by adding to a small amount of molten aluminum titanium alkali fluoride powder and alkali borofluoride powder in amounts such that titanium and boron are contained in the alloy in the ranges of 3.5 to 7.5 wt% and 0.1 to 0.3 wt%, respectively, and the ratio by weight of boron to titanium is about 1:2040 by weight, the melting temperature being kept below about 900C.
- the resultant molten alloy was skimmed and poured into a mold.
- Aluminum-titanium-boron mother alloys thus obtained were added to the casting mass of molten aluminum of 99.7% purity held in a 2-ton melting furnace at 750C to give a content of titanium of 0.025 wt%.
- the molten aluminum was stirred and kept at the same temperature for a predetermined time as specified in Table I.
- the molten aluminum was then cast into cylindrical ingots 200 mm in diameter and cooled with water.
- the resulting ingots were inspected by a polarizing microscope to determine the diameter of the crystalline grains therein. The average diameter for 400 crystalline grains for each such inspection is specified in the table, together with the character of the crystalline structure of the alloy in each sample.
- the attached drawings are reproductions of microphotographs showing the crystalline microstructure of a commercial grain size reducing aluminum-titaniumboron mother alloy vs an alloy according to the invention. They also compare the crystalline macrostructure of ingots cast from molten aluminum, to which these mother alloys had been added, after holding the molten aluminum for a long time.
- FIG. 2b shows crystalline macrostructure of an ingot obtained in the same manner but using the alloy specified for FIG. lb according to the invention.
- the ratio of boron/titanium contained in the alloy be about 1:2040 and preferably l/35 to l/25 when maximum improvement is required. Also, it is essential to form the mother alloy at fusion temperatures not exceeding about 900C.
- the mother alloys are designed to be added in small quantities to the molten casting aluminum and is used in a diluted state. Therefore, the lower limit of the quantity of titanium and boron in the alloy is not an essential limitation on the usefulness of the alloy. However, an extremely low content of titanium and boron is not desirable from the standpoint of economy, since the alloy has then to be added in very large quantities to the molten aluminum to make its influence felt. According to the invention, the lower limits of content of titanium and boron are set at 3.5 wt% and 0.1 wt%, respectively. These limits are selected somewhat arbitrarily purely on the basis of what is most economic for use in the art and hence must not be given undue importance.
- the titanium alkali fluoride powder and alkali borofluoride powder added in this manner are chemically reduced by molten aluminum and become dispersed into the mass aluminum as a metallic component of the alloy. Local formation of free titanium and boron metal in high concentrations in the molten aluminum should be avoided because they tend to produce undesirable crystal structures in the resulting alloy and decrease the duration of the grain size reducing effect.
- the molten casting aluminum should be slowly stirred to distribute the added powders on the free metal as uniformly therethrough as possible.
- the molten metal mass to which titanium alkali fluoride powder and alkali borofluoride powder are thus admixed is allowed, if necessary, to stand for a very short time to float the residues produced as a byproduct of the reduction reaction to the surface for easy separation. After removal of these residues, the molten alloy is poured rapidly into a mold, thereby obtaining an aluminum-titanium-boron mother alloy containing substantially the predetermined content of titanium and boron.
- the melting time is desirably limited to less than 30 minutes after the addition of the powder to the molten aluminum mass.
- alkali is intended to include potassium, sodium and any other equivalent alkaline cations having the capacity of forming fluoride complexes with titanium or boron.
- other complexes of these metals which are adapted to be reduced to release the free metal on contact with molten aluminum and give by-product residues that can be conveniently removed without deleteriously affecting the advantageous properties of the mother alloys could be substituted for those specifically identified within the scope of this invention.
- the size of the powdered form of these complexes is not critical and can be any size suitable for generally uniform distribution in the molten aluminum mass and for chemical reduction to free metal within the relatively short period named above. A particle range of about 20l00 mesh is satisfactory for these requirements but other sizes could be useful.
- An aluminum-titanium-boron mother alloy for addition to molten casting aluminum to promote the for' mation in the solid castings of a uniform small grain crystalline structure, said mother alloy consisting essentially of aluminum containing from about 3.5 up to about 7.5% by weight titanium and from about 0.1 up toabout 0.3% by weight boron in a weight ratio of titanium to boron of 20-4011 and being substantially free of acicular crystals.
- a method of preparing an aluminum-titaniumboron mother alloy for addition to molten casting aluminum to promote the formation of a uniform small grain crystalline structure in the solid castings which comprises the steps of adding to a molten mass of aluminum maintained at a temperature of less than about 900C finely divided particles of an alkali titanium fluoride complex and of an alkali boron fluoride complex in amounts sufficient to give a content of titanium and boron of from about 35 up to 7.5% by weight and from about 0.1 up to 0.3% by weight, respectively, in a weight ratio of about 20-40:l, said complexes being chemically reduced by said aluminum to free metal, mixing said aluminum mass to generally uniformly distribute said titanium and boron through said aluminum, and recovering the resultant mother alloy.
