What is better for vibration cast iron or mild steel?
Typically mild steel can withstand vibration better because it has a higher density than the more brittle cast iron but cast iron may be better at absorbing vibrations than mild steel, due to its lower density.
What is sound velocity in grey cast iron?
The sound velocity in grey cast iron typically ranges from 2400 to 3100 m/s, depending on factors such as microstructure, composition, and temperature. It can be affected by the presence of graphite, as well as the amount and distribution of other constituents in the material.
How malleable iron is produced?
Malleable iron is produced by heating white cast iron to a specific temperature range and holding it there for a specific period of time. This process, known as annealing, causes the carbon in the cast iron to form irregularly-shaped graphite nodules, giving malleable iron its unique properties of strength and ductility.
Is ductile iron generally conductive?
Yes, ductile iron is conductive. Its electrical conductivity is similar to that of gray cast iron due to the presence of graphite in its microstructure. This makes it a good choice for applications where electrical conductivity is required.
Do metals have high brittleness?
Metals generally exhibit low brittleness and are typically known for their ductility, allowing them to deform without breaking. However, certain conditions, such as low temperatures or specific alloy compositions, can increase brittleness in some metals, like high-carbon steel or certain cast irons. In these cases, the metal may fracture easily under stress rather than bending. Overall, while metals can exhibit brittleness under specific circumstances, they are primarily characterized by their ability to withstand deformation.
How can undercooling be minimized?
By adding "inoculant" to the liquid iron just before casting, undercooling can be minimized. Inoculation is a means of controlling the structure and properties of cast irons by increasing the number of nucleation sites available for the growth of graphite flakes in grey irons or graphite nodules in ductile irons.

Why cast iron is good for machine bases?
Grey cast iron is good for machine bases due to its capacity of absorbing vibration. This can be explained through its microstructure, where graphite works as great shock absorber.
How does the shape of graphite in cast iron affect its properties?
The shape of graphite in cast irons has the following basic forms: (a) Flakes. Graphite flakes have sharp edges which act as stress raisers in tension. This shape makes cast iron low in tensile strength and ductility, but it still has high compressive strength. On the other hand, the flakes also act as vibration dampers, a characteristic important in damping of machine-tool bases and other structures. (b) Nodules. Graphite can form nodules or spheroids when magnesium or cerium is added to the melt. This form has increased ductility, strength, and shock resistance compared to flakes, but the damping ability is reduced. (c) Clusters. Graphite clusters are much like nodules, except that they form from the breakdown of white cast iron upon annealing. Clusters have properties that are basically similar to flakes. (d) Compacted flakes. These are short and thick flakes with rounded edges. This form has properties that are between nodular and flake graphite. © 2008 Pearson Education, Inc., Upper Saddle River, NJ. All rights reserved.
How many types of irons are there?
There are generally three main types of irons used in golf: forged irons, cast irons, and hybrid irons. Forged irons are made from a single piece of metal and offer a soft feel and more control. Cast irons are created by pouring molten metal into a mold, allowing for more intricate designs and greater durability. Hybrid irons combine features of both irons and woods, making them versatile options for players.
