Definitions

  • the present invention relates to a piston for internal combustion engines and a method for producing a piston for internal combustion engines.
  • steels are used for the production of pistons for internal combustion engines, which have a significant decrease in strength at temperatures of more than 500 ° C.
  • examples of such steels are so-called tempering steels (eg 42CrMo4) or AFP steels (eg 38MnVS6).
  • the DE 35 18 058 A1 discloses a piston for internal combustion engines, wherein the piston consists at least partially of an iron-aluminum-chromium alloy having the following composition: 12 mass% Al, 10 mass% Cr and a balance (mainly Fe).
  • the EP 1 132 490 A1 shows a metal-matrix composite consisting of a light metal alloy and reinforcing components in the form of metallic fibers.
  • the reinforcing components in turn consist of an alloy containing mainly iron and 5 to 30% chromium and aluminum and / or silicon.
  • the present invention has for its object to provide a piston for internal combustion engines, which has particularly advantageous rheological properties, in particular with regard to the strength at higher temperatures.
  • the invention has for its object to provide a method for producing such a piston.
  • the object underlying the present invention is achieved by a piston having the features of claim 1.
  • the object underlying the present invention is achieved by a method having the features of claim 6.
  • the subclaims relate to advantageous developments of the invention.
  • the alloy may contain up to 5% by mass, in particular 3% by mass and particularly advantageously only 1.5% by mass impurities. It has been found that such a piston has a particularly high strength at temperatures of more than 500 ° C and thus has significantly better high temperature properties than conventional steels, which are commonly used for the production of pistons for internal combustion engines.
  • the piston according to the invention can be, for example, a piston for a diesel engine, in particular for a direct-injection diesel engine. It has been found that the use of the piston according to the invention in direct-injection diesel engines is particularly advantageous because the piston has particularly advantageous strength properties, in particular in the temperature range of about 500-600 ° C.
  • the iron-aluminum-chromium alloy has a density between about 6 g / cm 3 and about 7.5 g / cm 3 . This results in a significant reduction in the mass of the piston compared to that of the Prior art known pistons, which are made of conventional steels.
  • the conventional steels have a density of the order of about 7.8 g / cm 3 .
  • the piston may consist of at least two parts.
  • a first of the at least two parts of the piston consists of aluminum and that a second of the at least two parts of the piston consists of the iron-aluminum-chromium alloy.
  • the part of the piston facing the combustion chamber due to the advantageous high-temperature properties, may in particular be the second part of the piston made of the iron-aluminum-chromium alloy.
  • the iron-aluminum-chromium alloy preferably has an aluminum content of about 16% by mass.
  • the aluminum-chromium alloy has a chromium content of about 5.5 mass%.
  • the piston is made of at least two parts.
  • a first of the at least two parts of the piston is made of aluminum and that a second of the at least two parts of the piston made of the iron-aluminum-chromium alloy.
  • the thermal expansion coefficient of the second part of the piston substantially corresponds to the thermal expansion coefficient of the first part of the piston, which consists of aluminum.
  • the piston is produced by casting.
  • the piston is produced thermomechanically. Due to the simultaneous thermal treatment and plastic deformation, the rheological properties of the piston can be specifically adapted.
  • An inventive piston for internal combustion engines consists at least partially of the above-mentioned iron-aluminum-chromium alloy.
  • the piston can be produced, for example, by casting or thermomechanically.
  • the iron-aluminum-chromium alloy has a lower strength at low temperatures than the tempering steel (42CrMo4) and the AFP steel (38MnVS6).
  • the strength of the iron-aluminum-chromium alloy decreases in contrast to the rest in Fig. 1 almost never seen over wide temperature ranges. It can be seen that in a temperature range of about 500 - 600 ° C, the yield strengths of the iron-aluminum-chromium alloy are considerably larger than in the conventional tempered steel or AFP steel.
  • the iron-aluminum-chromium alloy has a substantially constant yield strength of more than 400 MPa, whereas the yield strengths of the other steels decrease drastically in this temperature range.
  • the density of the iron-aluminum-chromium alloy from which the piston is made wholly or partly in the range of about 6 g / cm 3 to about 7.5 g / cm 3 , compared to conventional steel alloys have a density of the order of 7.8 / cm 3 , significant weight reductions can be achieved.
  • the piston may be made in one or two parts, in the latter embodiment, for example, a first part of the piston of aluminum and a second part of the piston of the iron-aluminum-chromium alloy having an aluminum content of about 15 to about 17% by mass, preferably with an aluminum content of about 16% by weight and with a chromium content of about 4 to about 6% by mass, preferably with a chromium content of about 5.5% by mass. It has been shown that with this aluminum and chromium content both parts of the piston have substantially identical coefficients of thermal expansion, so that thermal stresses can be largely avoided.
