KISAKU IBE, OF NOGI GUN, SHIMANE KEN, JAPAN.

Specification of Letters Patent. Patented Oct, 19,1920.

To all whom it may concern:

Be it known that I KISAKU IBE, a subject of the Emperor of japan, and resident of 2107 Yasugi, Yasligi Machi, Nogi Gun, Shimane Ken, the mpire of Japan, have invented a new and useful Alloy, of which the following is a specification.

My invention relates to an alloy produced by fusing iron, titanium, and vanadium through the medium of silicon.

An object of my invention is to provide an alloy of the nature described economically by increasing the alloying functions of titanium and vanadium.

Another object of my invention is to provide an alloy better suited as material for general castings.

Other objects and advantages to be derived from the use of-my invention will appear from the following detailed description and the claim.

It is a recognized fact that titanium and vanadium are efficient deoxidizers, and that cast iron or steel produced by mixing these metals with iron is possessed of remarkable degree of resistance against high degrees of heat and high degrees of pressure. But then alloying functions of said metals are inefficient and only a small amount can be taken up and comprised in the alloy produced, these precious, rare metals are wasted thus rendering the product very costly. My invention improves this sort of alloying Serial No. 250,132.

method and effects considerable economy by savlng these metals through the medium of SlllCOIl.

In producing the alloy, I fuse one to five per cent. .(15%) of titanium and one to five per cent. (15%) of vanadium together with a certain amount of iron, in the presence of five per cent. or more of silicon, in an electric furnace or crucible. Good results may be obtained, however, when corresponding amounts of ores of these metals are mixed and reduced in an electric furnace or the like, and is formed into an alloy at the same time, as the case may be.

In my invention, nearly all the amount of the titanium and vanadium added is taken up and comprised in the alloy produced, and the product is far superior to an ordinary ferrosilicon, ferrotitanium or ferrovanadium, and may be used very economically and with good advantage as material for general castings.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

An alloy consisting of from one to 5 per cent. of vanadium, from 1 to 5 per cent. titanium, 5 or more per cent. of silicon and iron or steel.

In testimony whereof I affix my signature hereto.

KISAKU IBE. [L. 5.]
