United States Patent -O TITANIUM-SULFUR ALLOYS Harry P. Croft, Greens Farms, Conn., assignor to Kennecott Copper Corporation, New York, N. Y., a corporation of New York Application July 3, 1952, Serial No. 297,125 4 Claims. (Cl. 75-l75.5)
This invention relates to titanium alloys and, particularly, to binary alloys of titanium and sulfur.
Titanium vin unalloyed form possesses many useful properties for commercial applications. However, for some applications it is desirable to provide a metal having strength properties superior to those of the unalloyed form, yet retaining adequate ductility and hardness.
It is, therefore, an object of this invention to provide alloys of titanium which possess improved strength properties with respect to unalloyed titanium, and which possess commercially feasible properties of ductility and hardness.
It is another object of this invention to provide binary alloys of titanium and sulfur.
Other objects and advantages of the present invention will be apparent in view of the following detailed description thereof, especially in view of the attached drawing wherein the properties of the alloys of this invention are illustrated graphically.
In general, this invention relates to binary alloys of titanium and sulfur wherein the sulfur content varies from about 0.02% to about 0.70% and the balance is essentially all titanium. A preferred alloy range is delined by 0.02% to 0.35% sulfur, balance titanium.
The alloys of this invention may conveniently be prepared by arc-melting techniques. The base material may be either magnesium-reduced titanium or the iodideprocess type or titanium metal produced by any other method. Sulfur may be added to the charge in any of its forms. For example, it is convenient to add sulfur as TaS4 or any similar sulfurbearing compound. The melting technique may comprise charging a crucible with titanium metal and the sulfur or sulfur-bearing compound, and melting. After melting and casting, the ingots may be machined to chips and remelted to elect a more homogeneous distribution of the alloying addition. V i

1 Balance titanium.
To further illustrate the beneficial elects of sulfur additions to titanium, the above data have been presented in graphic form in the attached ligure. It will be apparent upon reference to this drawing that the alloying of titanium with sulfur results in increased strength accompanied by good retained properties of ductility and hardness.
As has previously been noted, the titanium basis metal for the alloys of the present invention may be of the type produced by the magnesium chloride reduction method, or by the iodide method, or by Vany other process. Such basis metal may include small amounts of certain impurities, such as carbon, iron, nitrogen, or the like.
In view of the above disclosure, it will now be clear that new and useful alloys of titanium and sulfur have been discovered and described. Accordingly, these alloys are hereinafter more particularly and specifically described in the claims.
What is claimed is:
l. Titanium-base alloys consisting essentially of from about 0.02% to about 0.70% sulfur, said alloys being characterized by a tensile strength of at least about 82,400 p. s. i. and an elongation of at least about 10%.
2. Titanium-base alloys consisting essentially of from about 0.02% to about 0.35% sulfur, said alloys being characterized by a tensile strength of at least about 82,400 p. s. i. and an elongation of at least about 20%.
3. Titanium-base alloys consisting of from about 0.02% to about 0.70% sulfur, balance titanium, said alloys being characterized by a tensile strength of at least about 82,400 p. s. i. and an elongation of at least about 10%.
4. Titanium-base alloys consisting of from about 0.02% to about 0.35% sulfur, balance titanium, said alloys being characterized by a tensile strength of at least about 82,400 p. s. i. and an elongation of at least about 20%.
