Description

GREY CAST IRON ALLOY AND CAST INTERNAL COMBUSTION ENGINE COMPONENT
BACKGROUND OF THE INVENTION
1. Field of the invention
The present invention concerns a grey cast iron alloy. More specifically, the present invention concerns a substantially pearlitic grey cast iron comprising further alloying elements for improved fatigue strength.
The invention further concerns an internal combustion engine component, cast from grey cast iron alloy according to the invention.
2. Description of the prior art
Grey cast iron is a most attractive material for e.g. internal combustion engine blocks for vehicles due to a relatively low cost and yet good to excellent perform- ance. Compositions within quite a wide range are previously known, such compositions normally being a compromise between properties, such as tensile strength, wear properties etc., of the material as used and production properties, such as cost, machinability etc.
Thus, for cast internal combustion engine blocks a base material 0120 has a composition according to Table 1 below and a common standard alloy has a composition also according to Table 1, the Scania standard alloy providing a grey cast iron with a pearlitic structure and a sound (pore free) material due to a comparatively high carbon content. However, although fully acceptable at present, an improved fatigue strength is today desirable as a complement to the present properties and would extend the possible use of such a prior art grey cast iron.
It is an object of the present invention to provide a grey cast iron with a comparatively sound structure and offering good machinability properties and having, in addition, a substantially improved fatigue strength compared to that of a standard alloy.
It is a further object of the present invention to provide a grey cast iron internal combustion engine component, such as an engine block, having a substantially improved fatigue strength compared to that of a standard alloy.
SUMMARY OF THE INVENTION
The object of the present invention is obtained by a grey cast iron according to the accompanying claim 1. Preferred embodiments are specified in the dependent claims.
Further, the object of the present invention is obtained by a grey cast iron internal combustion engine component according to the accompanying claim 9. Preferred embodiments are specified in the dependent claims.
BRIEF DESCRIPTION OF THE DRAWING
Fig. 1 shows Wδhler fatigue curves for a base alloy, a standard alloy and an alloy according to the invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
In the following description all percentages given for elements in the alloys specified are given as percentage by weight. The alloy according to the present invention is a grey cast iron having a substantially pearlitic structure, the carbon content being 3.2 - 3.49 %. The comparatively high carbon content promotes a sound structure. Additions of 0.2 - 0.4 % chromium, having pearlite/carbide stabilizing properties, provides a fine pearlitic structure.
Additions of 0.1 - 0.4 % molybdenum, 0.03 - 0.3 % vanadium, 0.007 - 0.015 % titanium and < 0.15 % niobium act, in addition to their carbide forming properties, as nuclei providing a fine pearlitic and flake graphite structure as cast (both as pri- mary and secondary precipitated carbides). Molybdenum also stabilises pearlite at elevated temperatures.
Silicon is present in an amount of 1.8 - 2.2 % promoting grey iron formation.
0.3 - 0.8 % manganese is present as a pearlite stabilizing agent.
Copper, here in an amount of 0.3 - 1.0 %, promotes pearlite formation and stabilizes the pearlite and also promotes the fine structure formation.
The content of sulphur and phosphorus should be held below 0.15 %.
Nitrogen, 0.005 - 0.017 %, compacts flake graphite and promotes pearlite formation, and aluminium, < 0.01 %, act as graphite formation agent.
The grey cast iron alloy further comprises iron and normal impurities to balance. The amounts of titanium, nitrogen and aluminium are in the normal impurity range but may be preferred. Examples:
1500 kg batches were prepared, each batch being cast to four 300 kg engine blocks, casting starting at 1420°C and the temperature dropping about 10°C during the casting procedure.
Ten different combinations, batches, of molybdenum, vanadium, titanium and niobium, using a base alloy, were produced.
Further, the nitrogen and aluminium content was varied in 16 different batches with different nuclei forming agents (inoculants).
Fatigue test samples were taken from each casting and fatigue tests were performed.
Still further, batches combining the composition showing the best results from the previous tests were produced and fatigue tested.
Results are shown in Fig. 1, curve 3 corresponding to compositions within the com- position ranges according to the invention, this composition also being shown in Table 1.
The grey cast irons according to the invention offer about 40 % higher fatigue strength than a grey cast iron base alloy and about 30 % higher fatigue strength than a standard engine block grey cast iron and still offering a grey cast iron which fulfils high performance with respect to machinability, soundness, etc.
As mentioned above, the grey cast iron alloy according to the invention is extremely useful for internal combustion cast engine components, such as engine block com- ponents, the alloy combining machinability, soundness and high fatigue strength. The alloy is also useful for other components such as cylinder heads, etc. Table 1. Grey cast iron compositions, % by weight, according to prior art and the invention
