Definitions
- Pistons for an internal combustion engine Internal combustion engine having a piston and using an iron-based alloy
- the present invention relates to a piston for an internal combustion engine and an internal combustion engine with such a piston and the use of an iron-based piston
- alloying elements in steel are crucial for the formation of the properties and this is used in the conventional steels mentioned above.
- the addition of chromium causes an increase in oxidation resistance, an increase in strength, a reduction in thermal conductivity but also an increase in material costs.
- the addition of molybdenum causes an increase in oxidation resistance, an increase in (hot) strength but also an increase in material costs.
- the addition of vanadium increases the (hot) strength but also increases the material costs.
- niobium causes grain refinement, the formation of carbides and nitrides and a reduction in toughness and in turn an increase in material costs. This is also the case with the addition of tungsten, which also leads to an increase in (hot) strength.
- the invention described here is based on the object of providing a piston for an internal combustion engine, which consists of an iron-based or consists of a steel alloy that ideally combines and transfers the following in a positive way to the piston:
- thermomechanical Fatigue (TMF) d. H . adequate thermomechanical fatigue strength
- the piston according to claim 1 is a piston for an internal combustion engine, preferably a diesel engine, which has an iron-based alloy or consists of this as the piston material, which has the following alloying elements in percent by weight (% by weight or "% by weight”):
- Chromium (Cr) Chromium (Cr) :
- Si Silicon (Si) :
- V Vanadium
- Niobium (Nb) Niobium (Nb) :
- the iron-based alloy according to the invention can preferably be characterized or referred to as high-alloy steel and more preferably as heat-treatable steel.
- the contents of relevant alloying elements have been further increased.
- the iron-based alloy of the piston is characterized in particular by the alloying elements chromium, molybdenum, tungsten, niobium and vanadium, which are used in greatly increased amounts compared to the previous series alloys 42CrMo4 and 38MnVS6 to achieve improved oxidation resistance and sufficient high-temperature (alternating) strength.
- the chromium content is advantageously selected to be comparatively high.
- the piston material according to the invention therefore represents an iron-based alloy or. a steel that has increased oxidation resistance and sufficient strength at high temperatures and under TMF stress.
- the piston material is nevertheless still easy to weld (e.g. by inductive welding, friction welding and/or laser welding) and can be machined.
- the thermal conductivity is not too low and within a usable range.
- the material costs are still within an acceptable range.
- the piston according to the invention represents an optimal compromise between material properties and material costs, in particular when it comes to optimized oxidation resistance at high temperatures.
- the iron-based alloy of the piston can also in percent by weight (% by weight):
- Chromium ( Gr ) 9 , 0 up to and including 12 , 0 and/or
- the iron-based alloy is a steel of the type X10CrMoVNb9-l or X22CrMoV12-l, i. H . consists of these . These steels are readily available and can be used directly to produce the piston according to the invention with its positive properties.
- the iron-based alloy of the piston according to the invention is advantageously a heat-treated alloy that has or consists of at least one tempered structure, preferably tempered martensite and/or an intermediate structure, preferably bainite, and optionally has a ferrite content of ⁇ 10% in the structure. It is preferred that the alloy has or has one or more of the above types of structure. consists of . Furthermore, the alloy according to the invention is preferably a tempering steel which is tempered by tempering d. H . a combination of hardening and subsequent tempering or optional bainitizing is produced.
- the existing carbide formers Gr, Mo and V decisively change the formation mechanism of carbides formed during tempering.
- tempering and tempering achieves a particularly important combination of properties, namely a yield point that is still adequate, combined with a high level of ductility, which is important for safety against brittle fracture, e.g. B. the notched impact strength . Therefore tempering of the tempering structure is carried out at at least 400°C.
- a further aspect of the present invention is an internal combustion engine, in particular a diesel engine, with a piston according to the configurations described so far.
- the piston according to the invention transfers all of its technical advantages to the internal combustion engine, which contains the piston as a component.
- the present invention includes the use of the previously defined iron-based alloy in all its configurations, preferably in the form of the above steels of the type X10CrMoVNb9-l or X22CrMoV12-l, for pistons of an internal combustion engine, in particular a diesel engine.
