Definitions
- AlSiCu alloys AlSiMg alloys are mostly used, which have a favorable strength / expansion ratio after the heat treatment.
- this alloy has the significant disadvantage that it has a very low heat resistance or aging resistance, which is expressed in the TMF (Thermo Mechanical Fatigue) or thermomechanical fatigue test by a low dynamic strength component.
- the object of the invention is to provide a thermally shock resistant aluminum alloy good castability.
- the Al cast alloy according to the invention has a good castability while avoiding, at least significant reduction of brittle phase components that promote the crack initiation and crack propagation in the thermo-mechanical fatigue. At the same time it has a high heat resistance / aging resistance. However, despite its high resistance to aging, it is associated with an output strength reduction to achieve high lifetimes.
- the silicon content 4.5 to 6.0 wt.%, Brittle phases are avoided with sufficient castability.
- the low copper content of at most 0.45, preferably at most 0.35 wt.% To avoid brittle phases, but at the same time ensures a low initial strength with sufficient heat resistance.
- the castings of the invention alloy are preferably subjected to a heat treatment consisting of a solution annealing between 470 to 540 ° C, quenching with water and optionally air and then a hot curing for several hours at about 160 to 250 ° C.
- the casting alloy according to the invention is particularly suitable for chill casting, especially for the core components of internal combustion engines, in particular the engine block / crankcase and cylinder head and, especially in the automotive industry. Due to the high heat resistance / aging resistance, it is particularly suitable for engine core components with constraint-intensive component geometry, ie for engines with closely spaced combustion chambers and tightly dimensioned valve webs.
- the damage parameter (P SWT ) according to Smith, Watson and Topper was determined at a maximum temperature of 250 ° C and a minimum temperature of 50 ° C, which is a measure of the damage and derived for the aging resistance.
- the load cycle time of the specimens was determined.
- specimens were prepared from several cylinder heads, which were cast from the aforementioned AlSi7Mg alloy of the standard composition (DIN EN AB 42100) and subjected to the same heat treatment.
- specimens were made of a plurality of cylinder heads made of an alloy similar to the AlSi7Mg alloy mentioned in the above-mentioned Comparative Example 1, except that instead of a copper content of less than 0.02 wt.%, a copper content of 0.45 to 0.55 wt.% had.
- the damage parameter (P SWT ) and the number of cycles were determined under the same conditions as in Example 1.
- alloy Damage parameter P SWT in MPa Load cycle number N example 0.29 to 0.38 2650 to 4100 AlSi5 Mean 0.35 Mean 3555
- Example 1 0.22 to 0.27 1710 to 3300 AlSi 7Mg Mean 0.22 Mean 2555
- Example 2 0.41 to 0.53 1580 to 2250 AlSi 7MgCu0,5 Mean 0.48 Means 1900
- thermal conductivity of the alloy according to the invention was also determined. It is at the same high level as the thermal conductivity of the alloy 1 and significantly higher than that of the alloy according to Comparative Example 2.
