Definitions
- Titanium and titanium base alloys hereinafter referred to as titanium, are characterized by excellent.
- One way to lessen the costs of parts and equipment made from titanium and to thereby increase its usage is to use it in composites in which a layer of dissimilar and less expensive metal is sandwiched between-two layers of titanium or between one layer of titanium and another corrosion resistant metal; e.g. stainless steel.
- Plain carbon steel is relatively inexpensive and characterized by goodmechanical prop erties. For example, it is a good heat conductor and would not detract from titanium in heat exchanger applications.
- the use of plain carbon steel is, however, accompanied by potential dangers. Interstitial elements, carbon, oxygen, and nitrogen and particularly carbon, can diffuse from plain carbon steel into titanium and especially into the plain carbon'steel-titanium interface, and thereby detrimentally affect its properties, and particularly its ductility. Exemplifying this are 1 hard and brittletitanium carbides which form in titanium metal when carbon is present in amounts of approximately 0.15% and higher.
- the present invention overcomes the potential .dan-
- the article of the present invention is a composite comprised of at least two metallic layers.
- One of the layers is a metal from the group consisting of titanium and titanium base alloys and another is steel.
- the steel is a plain carbon steelhaving up to 1.5% carbide former present in a carbide former-to -carbon ratio of from 1.5 to 25.
- carbide former refers to one or more of the elements which have a strong affinity for carbon, and preferably to titanium and columbium.
- the amount of carbide former is limited to 1.5% and preferably to 0.75%, as the benefits obtained from further increases in the level of carbide former are disproportionate with regard to the costs involved.”
- the ratio of carbide former-to-carbon in the plain carbon steel should be between about 1.5 and 25. This means that the weight percent of carbide forming elements should be between 1.5 and 25 times the weight percent of carbon.
- a minimum carbide former-tocarbon ratio of at least 1.5 is imposed to insure sufficient carbide former to substantially preclude carbon. migration from the plain carbon steel toward and into the titanium and topreclude the formation of enriched carbide areas, which are associated with decreased drawability.
- Composites formed from plain carbon steel with carbide former-to-carbon ratios of 1.5 to 5 are often preferred as they generally have higher yield strengths than similar composites formed from plain carbon steel with carbide former-to-carbon ratios in excess of 5.
- composites having carbide former-to-carbon ratios in excess of 5 are often preferred as they are more workable than those'having ratios below 5. Yield strengths of the composites decrease and elongations increase with increasing amounts of carbide former.
- An upper carbide formerto-carbon ratio of 25 is imposed as the grain-size of the plain carbon steel can become undesirably large at higher ratios.
- a maximum carbideformer-to-carbon ratio of 15 is often desirable since a range of from 5-15 has proven to provide an optimum combination of drawability and cost.
- the article of the present invention is comprised of a layer of titanium',.a layer of stainless steel, and. a layer of plain carbon steel containingcarbide former sandwiched therebetween.
- Composites of this nature areparticularly desirable in applications such as condensor tubes or heat exchanger tubes wherethe inner surface of the tube which is exposed to hot chloride solutions could be titanium and where the outer surface which is exposed to air or decontaminated water could be stainless steel.
- the carbide former substantially precludes carbon migration from the plain carbon steel toward and into both the stainless steel and titanium.
- barrier metal between the plain carbon steel and titanium.
- the barrier metal is from the group consisting of nickel, cobalt, palladium, platinum, chromium and copper, as limited by those instances wherein their melting point does not preclude their use. Although no criticality is placed upon the thickness of the barrier metal, layers ranging in thickness from 0.0001 to 0.005 inch are believed to be beneficial.
- the titanium alloy can be an alpha alloy; e.g. 5% A1, 2.5% Sn, balance essentially titanium, an alpha-beta a1- loy; e.g. 8%.manganese, balance essentially titanium, or
- a composite article comprised of at least two bonded metallic layers: at least one of said metallic layers being a metal from the group consisting of titanium and titanium base alloys; at least one of said metallic layers being steel, said steel consisting essentially of up to 2% carbon, up to 0.6% silicon, up to 1.65% manganese, upto 1.5% carbide former, balance essentially iron, said carbide former being from the group consisting of titanium and columbium, said carbide former being present in a carbide former-to-car'bon ratio of from 1.5 to 25.
- An article according to claim 1 having-at least two layers from the group consisting of titanium and titanium base alloys, and wherein said layer of plain carbon steel is sandwiched between said layers of metal 7 from the group consisting of titanium and titanium base alloys.
- An article according to claim 1 including a layer metal being from the groupconsisting of nickel, cobalt,
