Why cast iron absorb vibrations

Question

Accepted Answer

Cast iron absorbs vibrations due to its high damping capacity and stiffness.

Cast iron has a high damping capacity, which means it can dissipate energy from vibrations.
It is also stiff, which allows it to resist deformation and maintain its shape under stress.
These properties make it ideal for use in applications where vibration damping is important, such as engine blocks and machine tool bases.
Cast iron can also be made with different compositions and microstructures to optimize its damping and stiffness properties.
For example, gray iron has good damping but lower stiffness, while ductile iron has higher stiffness but lower damping.

Accepted Answer

The graphite structures is cast iron especially the flaked formation in gray cast iron are especially good for absorbing vibration

Accepted Answer

Grey cast iron possesses this property due to the presence of carbon in the form of graphite flakes in the pearlite/ferrite matrix. The morphology of graphite as a flake in grey cast iron enables it to absorb both compressive and vibrational loads without initiating a crack.
