Iron-Chromium-Aluminium Alloy The invention relates to an iron-chromium-aluminium alloy having good oxidation resistance.
Although the catalytic converter is the rule in four-stroke-engines today, the development of catalytic converters for Diesel and two-stroke engines is still in its beginnings. In four-strokeengines, alloys are used which are similar to those described in EP-A 0387 670: with (in by weight) 20-25% Cr, 5-8 Al, max. 0.01 P, max. 0.01 Mg, max. 0.5 Mn, max. 0.005 S, residual iron and unavoidable impurities and, if required, alloying elements, such as 0.03 0 08 Y, 0.004 0.008% N, 0.02 0.04 0.035 0.07 Ti, 0,035 0.07 Zr. Since production by traditional methods, namely conventional pouring of the alloy and subsequent hot and cold deformation, is very difficult where aluminium contents of below 6% by weight are concerned and in cases of higher aluminium contents is no longer workable in large-scale productions, alternative production methods have been developed.
US-PS 5.366.139, for instance, discloses a method whereby foils of iron-chromiumaluminium alloys are produced by way of suitable iron-chromium steel being coated on both sides with aluminium or.aluminium alloys by way of roll cladding. This composite metal is processed exclusively by cold deformation and is subjected to diffusion annealing to produce a homogeneous structure.
A further method whereby the coating is achieved by way of hot dip aluminizing is disclosed in DE-A 198 34 552. The latter foil has the following chemical composition (all details in by weight): 18 25 Cr, 4 10 Al, 0.03 0.08 Y, max. 0.01 Ti, 0.01 0.05 Zr, 0.01 0.05 Hf, 0.5 1.5 Si, residual iron and method-associated impurities. Foils fabricated with this alloy were to date used in four-stroke-combustion engines.
P\WPDOCS\CRNNXLSpcc2590261 spcc doc.22/072008 2 It is the object of the present invention to produce an alloy for applications in the C temperature range of 250 0 C to 1000 0 C having an adequate oxidation resistance which is also achievable in large scale productions.
5 The present invention provides use of an iron-chromium-aluminium alloy having good N oxidation resistance with which semi-finished products are produced after melting of the 0 alloy by ingot or continuous casting or strip casting as well as by hot- and cold-forming, C N comprising (in by mass) 2.5 5% Al, 17 to 19% Cr and 0.05 to max. 0.6% Si as well as addition of> 0.01 to 0.1% Y and >0.01 to 0.1% Hf and 0.01 to 0.2% Zr as well 0o as production related impurities, in components of diesel vehicles or two-stroke devices, which components are adapted for use in the temperature range of between 250°C and 1000°C.
A preferred iron-chromium-aluminium alloy having good oxidation resistance has the following composition (in by weight): 2.5 5% Al and 13 to 21% Cr as well as alternative additions of: 0.01 to 0.1 Y and 0.01 to 0.1 Hf; 0.01 to 0.1 Y and 0.01 to 0.1 Hf and 0.01 to 0.2 Zr; 0.01 to 0.2 Cer composition metal (Ce, La, Nd); 0.01 to 0.2 Zr and 0.01 to 0.2% Cer composition metal (Ce, La, Nd) as well as production-associated impurities.
Surprisingly, it has been found that, in Diesel engines and two-stroke engines, aluminium contents above 5 are not required. 2.5 to 5.0 by weight are quite sufficient to guarantee an adequate oxidation resistance in the temperature range of 250 0 C to 1000 0 C which is of interest in this regard, as the examples presented below will show. Indispensable in this situation are the additions of reactive elements to guarantee the oxidation resistance.
Particularly proven are 0.01 0.1 Y and/or 0.01 0.1 Hf, where, in the presence of both elements, the sum of both these elements must not exceed 0.15 by weight, because at this W02004/081247 PCT/DE2004/000454 3 level the positive effect of the oxidation resistance will be reversed to a negative. However, also by adding other oxygen-affine reactive elements, such as for instance Zr, Ce MM and La, positive effects can be achieved in relation to the oxidation resistance of the alloy.
One method for the fabrication of semi-finished articles from this alloy is characterised in that the semi-finished article following melting of the alloy by way of ingot casting or continuous casting as well as hot and cold deformation may be required to undergo one (or more) intermediate annealing processes.
Advantageous embodiments of the method are described in the dependent claims.
The production of a foil of 50p or even 20g thickness is possible in the conventional manner in such compositions. The slabs can even be produced by way of the particularly inexpensive continuous casting process which in the presence of higher aluminium contents is, as a rule, connected with high losses.
Preferred applications for this alloy are: components in exhaust systems of Diesel engines in vessels, Diesel engines and twostroke engines of motor vehicles (cars, trucks) or motorbikes; substrate foils in metallic catalytic converters of Diesel engines and two-stroke engines; components in Diesel engine glow plugs; knitted metal fabrics and mats for exhaust cleaning systems used in for instance motorcycles, brush cutters, lawn mowers and power saws; components for exhaust cleaning systems for fuel cells; WO2004/081247 PCT/DE2004/000454 spraying wires for surface coatings of components employed in exhaust systems of diesel and two-stroke systems; heating conductors or resistance materials for electrical preheating of exhaust cleaning systems in Diesel and two-stroke systems.
The subject of the invention is described in greater detail in the following examples.
(Aluchrom ISE, Hf3 and Hf4 represent comparative alloys and Aluchrom Hfl and Hf2 are the subject of the present invention).

For instance, the alloys according to the present invention, Aluchrom Hfl and Aluchrom Hf2, in spite of their comparatively low Al-content of around show an extremely good oxidation resistance, which is similar to the comparative alloys Aluchrom ISE and Aluchrom Hf4. By comparison, Aluchrom Hf3, in spite of its high Al- content of 5.36%, has lower values which can be attributed to the Y content being too low. In this instance therefore additions of Y or Ce MM result in a markedly improved oxidation resistance. (compare Aluchrom ISE and Aluchrom Hf4).
A further important aspect for the construction of metallic catalytic converter substrates for Diesel engines and two-stroke engines is the dimensional stability of the foil during the useful life of the foil. A respective characteristic feature in this regard is the linear deformation which should, if possible, not exceed 4 W02004/081247 PCT/DE2004/000454 Dimensional Stability Linear deformation at 1100°C, 50 p foil thickness Lingeninderung bel 1100*C, 50pm Follendicke -AJC4uvAh I$ -Ahiciudn HFi -Afuctym M Aklnr Ht 3 0 50 100 18 200 250 00 350 400 450 AuElagerungsrait in SExposure time in [h] Linear deformation in This also shows that the alloys in accordance with the present invention, Aluchrom Hfl and Aluchrom Hf2, having an al content of around 3 achieve a dimensional stability of 4% as do the comparative alloys Aluchrom ISE and Aluchrom Hf4 having an al content of> Also in this case, in spite of their comparatively high Al content of 5.36 but too low a Y content, the comparative alloy Aluchrom Hf3 does not meet the requirements, since the linear deformation after 400 h, being about 5 is clearly too great.
Thus it is surprisingly found that with a suitable tuning of the oxygen-affine reactive elements, even where Al contents clearly below 5 are present, a dimensional stability necessary for the production of metallic catalytic converters can be achieved.
W02004/081247 PCT/DE2004/000454 A cost-effective production, based on the comparatively low Al contents, by way of ingot casting, continuous casting or even strip casting whilst observing the application-specific parameters is thus achieved.
