ALLOY OF MANGANESE AND TITANIUM AND METHOD OF PRODUCING THE SAME.

Specification of Letters Patent.

Patented Apr. 16, 1912.

No Drawing. Original application filed May f1, 1909, Serial No. 493,857. Divided and this application filed May 18, 1910.

Producing the Same, of which the following 1s a specification, my present application for patent being a division of my pending application, Serial No. 493,857, filed May 4, 1909, which is a division of Serial Nofsoaaso, filed March 22, 1907, now Patent No. 935,863.

My present invention relates, in part, to improvements in, and processes for producing, alloys, including those of copper with other metals, such as tin, zinc, or manganese, the latter being designated as manganese bronzes. A p

The copper of commerce contains impurities, and ithas been found that admixtures, or alloys therewith of certain metals, or elements, such as titanium, produce on such copper, for casting or other purposes, certain beneficial results, for instance reduction, diminution, or even elimination of undesired compounds or gases present in its molten state, and which cause defects such as pin-holes. tending to render such castings unsound and useless. cial copper itself, as say in the form of cast-- ings, has been thus purified and improved,

the introduction thereinto, in its remolten state, of manganese to produce special bronzes has hitherto produced in the bath a recurrence of conditions unfavorable to the copper and consequent unsoundness, if not uselessness, of the resulting bronzes. Thus for instance, into the alloy, in molten state, compounds have been imported and"resulting'gases developed and occluded, which owing to their maleficent effect, especially upon the copper content, have injuriously affected the alloy produced, even in cases in which the copper itself had been, as above stated, previously purified.

My tests have demonstrated that by introducing into the bath of molten copper employed in production of the bronze alloys referred to, manganese, itself previously improved by alloying with titanium, a satisfactory condition of the resulting alloy is While commer- Serial No. 561,934.

promoted. In addition to its utility for the specific purpose aforesaid, z. e. in making alloys of copper with manganese, or other metals, my novel alloy of manganese and titanium is also useful when comelted in small quantities with manganese to purify and improve the latter, and also in other employments in the arts. As titanium exists rarely, if ever, isolated in metallic state, but only as alloyed with other metal, principally iron, or sometimes copper, and none of these alloys serve my purpose, it is preferable to derive the required titanium from its oxid. I

The production of alloys comprising manganese and titanium may be practiced by my present invention as follows, viz:- ()xld ofmanganese, oxid of titanium and carbon are mixed together as for instance, per the formulae Said mixture, preferably together with some manganese, is charged into one of the now well-known forms of so-called electric furnaces, such for example as illustrated and described in Letters Patent No. 802,9t1, granted tome October 24th 1905, and the current turned on. This will result in production of a bath of molten manganese, and

the current being continued, the titanium N. Y., A CORPORATION OF due, under the conditions of industrial ,practice, to the diflicult-y of exactly proportioning the reducing agent so as to merely satisfy chemical afiinity therefor of the oxygen present without leaving some uncombined carbon. This circumstance is of no detriment to the product for many purposes, but will prove of advantage in certain special uses thereof.

Manganiferous iron ore may be substituted for the oxid of manganese as above described, enough'carbon bem in such case supplied to reduce the oxid 0 iron of such ore, as well as the oxid of manganese and the oxid-of titanium accordingto the formula In such case addition to the bath of the resulting molten iron assists the action of the molten manganese in facilitating the reduction of the titanic acid, and the resulting alloy comprising iron as well as titanium and manganese is advantageous for special purposes.

The proportions of the ingredients used in the charge will be varied according to the percentage of the respective metals desired in the alloy according to the formulas above given and as experience and test in each case will readily demonstrate to those skilled in the metallurgical art.

What I claim as new and desire to secure by Letters Patent is the following, viz

1. The method of producing the binary comprises reducing titanium oxid-by carbon in a bath of molten manganese, substantially as described. I

3. As a new article an alloy, or compound, consisting essentially of titanium and manganese alloyed together and containing also some carbon.

4. As a new article an alloy, or compound, consisting essentially of titanium and manganese alloyed together and containing also carbon in excess of 1% AUGUSTE J. ROSSI.
