Abstract
Si-Mo ductile cast irons are used to fabricate the exhaust manifolds of the internal combustion engines of large series cars. The maximum pointwise temperature at full engine load may be higher than 750°C, and the main damage mechanisms in service are high-temperature oxidation and thermo-mechanical fatigue. The mechanical behavior of a Si-Mo cast iron is studied as a function of temperature, by means of stress-life fatigue tests up to 10 million cycles, as well as tensile and compressive tests, followed by fractographic examinations, and the mechanical test results are correlated with both the cast iron microstructure and previous heat treatment.
