Definitions
- the invention relates to a spheroidal cast iron alloy for cast iron products with a high modulus of elasticity, the spheroidal cast iron alloy containing at least the elements C, Si, Mn, Cu, Mg, S and as admixtures Ni and / or Mo as non-iron components.
- Ductile iron alloys are used in motor vehicle construction for the production of cast parts which must have a high resistance to torsional moments, for example the crankshaft, as part of the engine in the
- the castings often have a very complex geometry with many areas that are subjected to different loads and therefore have different wall thicknesses. This requires a casting technique that is suitable for parts with highly differentiated geometries.
- the castings also often have to be post-treated.
- the aftertreatment can be a heat treatment and / or a machining treatment.
- An important property that is desired for such cast parts is an elastic modulus that is as high as possible. Alloys with a modulus of elasticity of up to approx. 160 GPa are currently usually used.
- a steel alloy is usually used for parts with the highest possible modulus of elasticity and the parts are then machined by forging. However, this manufacturing method is expensive.
- WO 99/19525 discloses a nodular cast iron alloy which can be used for shafts and disks of a disc brake.
- the alloy contains in percent by weight 1.5 to 4.5% C, 1.5 to 4.5% Si and at least 1.0 to 6.5% Mo, and possibly Ni and Cu, the sum (% Mo +% Ni +% Cu) not exceeding 6.5%, and as Balance iron and the usual impurities.
- the alloy is characterized by good resistance to high temperatures and abrasion.
- WO 96/38596 discloses a spheroidal cast iron alloy with a high modulus of elasticity.
- the alloy contains in percent by weight: 3.0 to 3.8% C, 2.0 to 2.6% Si, 0.2 to 0.6% manganese, less than 0.02% P, less than 0.03% S, 0.03 to 0.06% magnesium, 0.8 to 1.2% Ni, 0.8 to 1.2% Cu, 0.4 to 1.0% Mo and the rest Fe.
- Ductile iron alloys with high pearlite and graphite contents are known. With these known alloys, the modulus of elasticity is too low for certain applications. If the graphite content is kept low, the matrix portion becomes larger and the modulus of elasticity higher. There is more mixed crystal than graphite. ,
- the alloy is composed of percentages by weight: C ⁇ 2.9%, Si 3.8 to 4.3%, Cu 0.5 to 1.0%, Ni and / or Mo 0 to 4%, Mn 0.1 to 0.8%, Mg 0.03 to 0.07% and S at most 0.015%, whereby the mixture proportions C and Si are very close to the eutectic.
- the pearlite content in the structure of the cast iron products is reduced and that the alloy comes very close to the eutectic. This is achieved in that the pearlite content is less than 50 to 70%.
- the cutting properties are improved by the lower percentage of pearlite.
- the core idea of the invention is to provide a spheroidal cast iron alloy which is particularly suitable for crankshafts in internal combustion engines.
- the higher modulus of elasticity considerably reduces the risk of breakage, even in the case of a one-piece shaft with a geometry with alternately relatively small and large cross sections, and the life of the shaft is considerably extended.
- the rigidity of the crankshaft is also increased. As a result, the crankshaft runs more smoothly. Better smoothness also means that the vibrations that act on the bearings of the crankshaft are significantly reduced. As a result, the bearings and the shaft achieve a significantly longer service life.
- the C content is decisive for the modulus of elasticity of the crankshaft.
- GJS spheroidal graphite iron
- the structure consists of 60-70% pearlite, 30 to 40% ferrite.
- the total graphite content is 10%.
- the graphite formation is greater than 90% V and VI (according to DIN EN ISO 945) with a size of 6 to 7.
