Specification of Letters Patent.
To all whom it may mam! dizing and removing the sulphur) ,is greatly Be it known that we, HANS GoLnsoHMm'r and OTTO WEIL, subjects of the King of Prussia, German Emperor, and residents'of Essen-on-the-Ruhr, inthe Province of the Rhine, German Empire, have jointly invented certain new and useful Improvements in Titanium Alloys and Methods of Producing the Same, of which the following is a specification. I
Numerous experiments have shown that it is possible by an additionof titanium to improve considerably the quality of steel and .cast-iron.. The addition of titanium in a metallic state has been attempted, but on 1 account of the badalloying qualification, the
high melting point and the small specific weight of this meta1, the results obtained from such attempts have been entirely unsatisfactory, and because ,of this experts have been of opinion that'in order to obtain good results it is necessary to make use, instead of pure titanium, of aniron-titanium-alloy containing only from "10%to 15% of ti-' tanium. In manyca'ses, however,'it would have .been preferable, to add an iron-titanium-alloy containing a high percentage of titanium, but the same objections have been raised to the use of such an alloy as to the employment of metallic titanium, the objection in each case being tothe use of a high percentage of titanium.- c
As a result of our experiments we have found, as set forth in our original applicationSer. No. 587,857, filed Oct. 19, 1910, of which this application is a division, that an alloy containing a higher percentage of titanium than has been employed heretofore may be used to advantage in bathsofsteel and cast-iron if aluminum isyadded as .a third element, in which case we employ "an iron-titanium aluminum-alloy. By using such an alloy as this, with a higher percentfacilitated. The action takes place much more quickly than when an; alloy is used containing only from 10% to 15% of titanium. In practice it has been found advisable to use alloys containing from 15% to- 35% of titanium and a quantity of aluminum amounting to about 10% of the titanium present, that is to say, 1.5% to 3.5% of aluminum. The alloy may, however, contain a greater percentage of aluminum which in some cases seems advisable.- a
One of the principal advantages resulting from the addition of the aluminum 'is that the melting, point of the titanium alloy is lowered while the alloying qualification is considerably increased. Y
Iron-titanium-aluminum alloys suitable for the purpos'e herein described and of any desired composition may-be easily produced 15% of titanium and in which the aluminumpresent is ,at least 10% of the titanium.-
2.,As a' new product, an alloy of iron, titanium and aluminum containing 'app'roxi mately 24% of titanium and approximately 3% ofaluminum. a
, 3. As a'new product, an alloy of iron,
titaniumand aluminum containing at least 15% of tltanium and at least 1.5% of aluminum.
In witness whereof we have hereunto set our hands in the presence of two witnesses.
