Definitions
- the invention relates to a nodular cast iron alloy for cast iron products with a high modulus of elasticity, wherein the nodular cast iron alloy as non-iron components at least the elements C, Si, Mn, Cu, Mg, S and as Contains admixtures Ni and / or Mo.
- a nodular cast iron alloy is known, which for shafts and Discs of a disc brake can be used.
- the alloy contains in Weight percent 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, where the sum (% Mo +% Ni +% Cu) 6.5% does not exceed, and the remainder iron and the usual impurities.
- the Alloy is characterized by a good resistance to high Temperatures and abrasion.
- Spheroidal cast iron alloys with high pearlite and graphite content are known. at These known alloys, the modulus of elasticity for certain applications low. If the graphite content is kept low, the matrix fraction becomes larger and the modulus of elasticity higher. This results in more mixed crystal than graphite.
- the alloy is composed of Weight percent: 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%, S maximum 0.015%, and balance iron, in which the mixing proportions C and Si are very close to the eutectic.
- the mixed crystals can be guaranteed. This is achieved by the fact that the Si content is 3.8 to 4.0%.
- the core idea of the invention is to specify a nodular cast iron alloy which is particularly suitable for crankshafts in internal combustion engines.
- modulus of elasticity is the risk of breakage, even with a one-piece shaft with a Geometry with alternately relatively small and large Cross sections significantly reduced and the life of the shaft considerably extended.
- the rigidity of the crankshaft is also increased. This will be a Achieved smoothness of the crankshaft.
- a smoother running also means that the vibrations acting on the bearings of the crankshaft, considerably be reduced.
- the bearings and the shaft thereby achieve a much longer Operating life.
- the C content is decisive for the modulus of elasticity of the Crankshaft.
- Ductile iron alloys with carbon contents below 3.0% are not known yet. Usually included Ductile iron alloys 10 to 15% by volume graphite. With the here proposed Ductile iron alloy will for the first time have a maximum graphite content of 10% by volume sought.
- the structure consists of 60-70% perlite, 30 to 40% ferrite.
- the graphite content is a total of 10%.
- the graphite formation is greater than 90% V and VI (according to DIN EN ISO 945) with a size of 6 to 7.
