Definitions
- 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.
- 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.
- 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.
- Table 1 a composition according to Table 1 below
- 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.
- 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.
- Fig. 1 shows W ⁇ hler fatigue curves for a base alloy, a standard alloy and an alloy according to the invention.
- 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.
- additives 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:
- Fatigue test samples were taken from each casting and fatigue tests were performed.
- 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.
- 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
