Definitions

  • Iron-aluminum alloys can be subjected to high thermal loads exposed to oxidizing and / or corrosive effects Parts of thermal machines can be used. You are supposed to be there increasingly special steels and nickel-based superalloys replace.
  • the invention as set out in claim 1 lies based on the task of an iron-aluminum alloy develop, which develop at temperatures of more than 700 ° C characterized by good mechanical properties. Task of Invention is also a suitable use of this alloy.
  • the alloy according to the invention exhibits even at temperatures between 700 and 800 ° C still mechanical properties that their use in mechanically slightly stressed components enable.
  • the invention is distinguished Alloy due to excellent thermal shock resistance and can therefore be used to particular advantage in thermal cycling Share thermal systems, such as in particular Housing or housing part of a gas turbine or one Turbocharger or as a nozzle ring, especially for one Turbocharger.
  • the Alloy very inexpensive by casting or by casting and make rollers.
  • Another advantage of Alloy according to the invention is that its Components have only metals, which comparatively inexpensive and independent of strategic-political Influencing are available.
  • Alloy I (alloy according to a preferred embodiment of the invention): component At.% aluminum 16.00 chrome 5.00 niobium 1.00 Silicon 1.00 boron 3.53 titanium 1.51 carbon 300ppm zirconium 100ppm iron rest
  • Alloy II (state of the art alloy) component At%. Silicon 4.00 carbon 3.35 molybdenum 1.00 manganese 0.30 phosphorus 0.01 sulfur 0.05 iron rest
  • Alloy I was tested in an arc furnace under argon Shielding gas melted. The served as starting materials individual elements with a degree of purity of more than 99%. The melt became a cast body approximately 100 mm in diameter and cast about 100 mm high. The cast body was remelted under vacuum and also under vacuum in the form of round bars with a diameter of approx. 12 mm and approx. 70 mm Length, in the form of carrots with a minimum diameter of approx. 10 mm, a maximum diameter of approx. 16 mm and one Length of about 65 mm or in the form of disc-shaped discs with a disk diameter of 80 mm, a disk thickness up to 14 mm and a radius at the edge of the disc of approx. 1 mm shed.
  • the discus-shaped Discs along the disc axis each with a hole introduced a diameter of 19.5 mm.
  • From the round bars and carrots were made specimens for tensile tests.
  • the disks were used to determine the thermal shock resistance.
  • Appropriately sized test specimens for determining the mechanical strength and thermal shock resistance have been commercially available on a large scale Alloy II used as material for gas turbine housings and a related alloy with a 25% lower alloy Share of silicon and a 40% lower share Made of molybdenum.
  • the thermal shock resistance according to Glenny was determined with the help of the disc-shaped discs. Two disks per alloy were cyclically heated to 650 ° C in a fluid bed and then cooled to 200 C with compressed air. After a certain number of such heating and cooling cycles, the number of cracks possibly forming at the edge of the panes with a crack length greater than 2 mm was then counted. The total number of cracks occurring on both disks as a function of the number of cycles is given below for alloy I according to the invention and for the two alloys according to the prior art.
  • Alloy I invention
  • Alloy II further alloy (State of the art) 140 0 0 0 240 0 2nd 1 340 0 2nd 4th 540 0 4th 4th 740 0 4th 8th
  • the alloy according to the invention comparably outperforms usable alloys according to the prior art not only in terms of mechanical strength at temperatures higher 700 ° C, but also in terms of thermal shock resistance.
  • the alloy according to the invention can therefore with particular Advantage as a material for components of thermal systems are used, which at temperatures between 700 ° C and 800 ° C still have a relatively high mechanical strength, and which, like gas turbine housings, have strong temperature changes subject to.
  • niobium By adding 0.1 to 2 at% of niobium, the hardness and the Strength of the alloy according to the invention increased. Beside or Instead of niobium, tungsten and / or tantalum can also be used Proportion of 0.1 to 2 at% can be added.
  • a proportion of 0.1 to 2 at% silicon improves the Castability of the alloy according to the invention and acts favorable for their resistance to oxidation and corrosion. Silicon also increases hardness.
  • the thermal shock, oxidation and corrosion resistance of the alloy according to the invention is considerably improved. This is primarily due to the fact that finely divided titanium diboride TiB 2 then forms in the alloy.
  • a protective layer predominantly containing aluminum oxides forms on the surface of the alloy according to the invention.
  • the titanium diboride phase contributes to a substantial stabilization of this protective layer by the titanium diboride phase engaging in the protective layer, for example in the form of acicular crystallites from the alloy, and thereby causing the protective layer to adhere particularly well to the underlying alloy.
  • the proportion of boron should not be more than 5 at% and that of titanium should not be more than 2 at%, since otherwise too much titanium diboride will form and the alloy will become brittle. If the proportion of boron is below 0.1 at% and that of titanium below 0.01 at%, the thermal shock, oxidation and corrosion resistance of the alloy according to the invention deteriorate considerably.
