Background technology
Exhaust manifold, is connected with engine cylinder block, and the exhaust of each cylinder is put together into importing exhaust main, carried
The pipeline of difference.The automobile engine of early stage, the power of Unit Weight is low, and the efficiency of combustion of fuel is not high, the waste gas discharged
Temperature is no more than 500 DEG C.With the raising of car engine engine efficiency, delivery temperature brings up to 600~650 DEG C.In recent years, constantly
Improve automobile exhaust emission standard, the more notable work for improving exhaust manifold of the application of catalysis technique and worm gear supercharging technology
Temperature, has reached more than 750 DEG C.With the further raising of engine performance, the operating temperature of exhaust manifold will also be improved.With
This simultaneously, with the progress of engine technology, the structure of exhaust manifold is also complicated therewith, in addition in repeat state of temperature
Lower work, it is desirable to which exhaust manifold material will not only have good high-temperature behavior, also possess good casting character.
Therefore exhaust manifold must possess following characteristic：1st, good high-temperature oxidation resistance：Exhaust manifold is long-term in height
Worked under warm repeat state, the antioxygenic property of material at high temperature directly influences the service life of exhaust manifold.It is general
Logical cast iron, which obviously can not be met, to be required, it is necessary to add the high-temperature oxidation resistance that alloying element improves material in the material；2nd, it is steady
Fixed microscopic structure：In room temperature to operating temperature range, material should not undergo phase transition or reduce as far as possible phase transformation as far as possible.Because
Phase transformation can cause the change of volume, be allowed to produce internal stress or deformation, influence performance and the life-span of product.Therefore matrix material
The ferrite or austenite structure of material preferably stabilization.The failure mode of the cast iron part worked under the high temperature conditions is mainly showed
For the corrosion under hot conditions, after the composition phase oxidation in tissue, such as graphitic carbon, the volume of oxide is more than original volume, draws
Play the irreversible expansion of casting；3rd, thermal coefficient of expansion is small：Small thermal coefficient of expansion be conducive to reduce exhaust manifold thermal stress and
Thermal deformation, is conducive to improving the performance and service life of product；4th, excellent elevated temperature strength：Product must is fulfilled in high temperature
