Abstract
PURPOSE: To provide the vibration isolating semispherical graphite cast iron with excellent vibration absorbing capacity and strength obtained by a method wherein a shape of a graphite crystal is formed to an intermediate shape of a spherical and a flake like forms as well as the graphite cast iron with a carbon eq. of a specific value or more is subjected to austempering treatment.
CONSTITUTION: The semispherical graphite cast iron containing, in a wt% basis, 3.0W4.1% C, 1.5W40% Si, 4.3% or more carbon eq. (C+1/3 Si) and 0.01W 0.08% Mg is subjected to the austempering treatment. That is, the aforementioned semispherical graphite cast iron is heated at 920°C for 2hr. in an austenite range and, thereafter, subjected to isothermal transformation in a salt with a temp. of 240W360°C to convert a substrate texture to a Bainite texture. As the result, the objective vibration isolating graphite cast iron having a spheroidization ratio of 35W 70%, containing 7W15% graphite in an area ratio and comprising a Bainite texture of which a substrate texture has 10W40% residual austenite in an area ratio is obtained.
